This is not really a performance question — it is a drywall question. Ethernet is faster; MoCA is already installed. Here is how much faster, and whether it matters to you.
How this page is funded: some links here are affiliate links, and Mesh & Signal earns a commission if you buy through them. It costs you nothing extra, it never changes which product we rank first, and we do not publish a price we have not verified. Full disclosure.
Ethernet is faster and cheaper per link, so run it wherever you realistically can. MoCA exists for the far more common case where you cannot — and in a finished house with coax already in the walls, MoCA usually wins on every criterion except raw throughput.
The actual gap
A Cat6 run gives you a full 1 Gbps or 2.5 Gbps depending on the ports at each end, with sub-millisecond latency and essentially no variance. A bonded MoCA 2.5 link gives you a real-world figure in the high hundreds of Mbps to around 2 Gbps depending on the coax plant, with latency typically in the low single-digit milliseconds. Bonded MoCA 2.0 tops out around 1 Gbps.

The honest comparison for a home link between two rooms.
Scroll the table sideways to see every column.
Read that table as a whole and the answer is obvious: the performance column favours Ethernet, and the install column decides the purchase. In a house under construction or with an open ceiling, run cable. In a finished two-story house with coax in four rooms and no conduit, MoCA does the same job this weekend.
When coax is genuinely the better choice
The rooms already have coax and nothing else. This is most American houses built or renovated since the 1990s, and it is the whole reason MoCA exists.
You are renting. Adapters leave with you; a cable run through a landlord's wall does not.
The run crosses something you cannot drill. A masonry wall, a finished stairwell, a fire-rated ceiling.
You need the link in the next hour. Two adapters, two coax leads, done.
When Ethernet is worth the disruption
You are already opening walls. Renovation, a new floor, a basement being finished — pull cable while it is cheap.
The link feeds an access point you will keep for a decade. Most access points want PoE, which coax cannot carry, so a cable removes a power supply as well as a bottleneck.
Your plan is above 2 Gbps. At that point MoCA becomes the ceiling and a 10 GbE-capable cable run does not.
The coax plant is a mess. Amplified splitters, old RG-59 and unterminated stubs all cost MoCA throughput, and tracing them can take longer than running a cable.
Try this first
Fit the PoE filter, whichever you choose
A MoCA install needs a Point-of-Entry filter at the point where the provider's coax enters the house. It keeps your MoCA signal inside your own wiring — which stops neighbors on the same cable plant seeing it and stops the provider's signals interfering with it. It is an inexpensive part and skipping it is the single most common cause of a disappointing MoCA result.
You do not have to choose only one
The common real-world build is both: Ethernet for the runs that are easy, MoCA for the one room that is not. The wired and Wi-Fi hybrid network is exactly that pattern, and mesh systems do not care which medium carries their backhaul — ethernet backhaul for mesh Wi-Fi works over a MoCA pair as well as over a cable.
If coax is not available either, the remaining wired option is your electrical wiring: MoCA versus powerline is the comparison that follows this one, and are MoCA adapters worth it is the four-question version for people who have not decided on coax at all.
How we picked
We do not run a test lab. Rankings here are built from the manufacturers' published specifications, measurements taken by independent outlets that do have labs, and the structural reasoning on this site about what a given house or job actually needs. Every product was checked as currently sold before it was included. Where a figure appears it is attributed and linked in Sources; where we have no basis for a claim, it is left out. Our methodology sets out exactly what we will and will not assert.

ScreenBeam ECB7250K02Bonded MoCA 2.5 in a two-adapter kit. If you are choosing MoCA because running Ethernet is impossible, this is the tier that makes the compromise invisible on a gigabit plan.
TRENDnet TMO-313C2KTwo adapters with 2.5 Gbps RJ-45 ports, so the LAN side is not the bottleneck even if the coax side is. The straightforward buy for linking a router in one room to a TV, console or access point in another.
A complete point-to-point link with 2.5 Gbps ports
ScreenBeam ECB6200K02Bonded MoCA 2.0 with a ceiling around 1 Gbps. On a plan at or under a gigabit that ceiling is above your service, which makes the extra spend on 2.5 hardware pure headroom rather than performance.

+Coax is shielded, so unlike powerline it does not care how old or noisy your wiring is
+Turns a disused cable TV outlet into a 2.5 Gbps Ethernet port
+Ships as a pair, so there is nothing further to buy to make the link work
+The cleanest way to wire mesh backhaul in a house you cannot drill
What to watch for
−You need coax in both rooms, on the same splitter tree
−Usually needs a MoCA filter at the point of entry to keep the signal inside the house
−A third room means another kit — this pack has no single-adapter add-on

Common questions
Is MoCA as good as Ethernet?+−
Not quite, and close enough for almost every home use. Ethernet gives you the full port speed with sub-millisecond latency; bonded MoCA 2.5 gives you up to around 2 Gbps with a few milliseconds of added latency. For streaming, calls, work and gaming the difference is not something you feel.
Is MoCA faster than Ethernet?+−
No. A MoCA link is always slower than an Ethernet run of the same generation, because it is modulating data onto a shared coax plant rather than using a dedicated twisted pair. It is faster than Wi-Fi across a house, which is the comparison that usually matters.
Does MoCA add latency for gaming?+−
A few milliseconds, which is far less than the jitter Wi-Fi adds across a house. If you are choosing between MoCA and Wi-Fi for a console, MoCA wins decisively. If you are choosing between MoCA and a cable you can actually run, run the cable.
Can I mix MoCA and Ethernet on the same network?+−
Yes, and most good home networks do. A MoCA adapter presents an ordinary Ethernet port at each end, so the link behaves like a long cable as far as the rest of your network is concerned. Switches, routers and mesh backhaul all work across it unchanged.
