About the same as a good extender
The difference in one table. Row two is the cause of every other row.
Scroll the table sideways to see every column.
The only real question is whether you can get a cable to the spot. If yes, an access point is better in every measurable way at a similar price. If no, an extender is the only one of the two that works at all.
Choose an access point if…
A cable can reach the mounting point. Ethernet, or a MoCA link over an existing coax outlet, or powerline as a last resort. All three present as Ethernet.
The room matters. A home office, a media room, anywhere a halved throughput and extra latency would be felt.
You want it out of the way. A ceiling mount is both the best radio position in a house and the least visible.
You are in a dense building. Adjustable transmit power is a genuine advantage there, and extenders rarely offer it — the apartment page.
No cable can reach, and no coax outlet exists there. This is the honest majority case, and it is a perfectly good reason.
You are renting and cannot mount or drill anything.
You want it working in ten minutes with no app to learn.
The need is light. A smart plug, a camera, a spare room used for browsing.
You are not sure yet. Buy one with an Ethernet port and it becomes an access point the day you run a cable — the hedge is the point.
How they actually differ — the mechanism
An extender associates with your router as a client, then rebroadcasts. One radio, two jobs, so it passes on roughly half of what it receives — and it inherits whatever signal quality it can get from your router, so a marginal position gives you a marginal result amplified.
An access point receives a full-speed wired feed and spends all of its radio time serving your devices. It also gets to be somewhere sensible: a ceiling is the only genuinely unobstructed position in a house, and mounting there means the signal travels down through one floor instead of sideways through several walls.
There is a middle option worth knowing about, because it is cheap: many extenders have an Ethernet port and an access point mode. Feed one by cable and switch modes and you have, functionally, an access point — with worse antennas and no ceiling mount, but none of the throughput penalty. Extenders with an Ethernet port.
Worth knowing
And the mesh option
A wired mesh node sits between these two: about as good as an access point, and easier, because it joins a system you already own and roams properly by default. If you already have a mesh system with Ethernet ports, wiring one of its nodes is the best-value version of this entire decision — mesh systems with Ethernet ports.
The case against both
If more than two rooms are bad, neither a single extender nor a single access point is the right scope — you need a system. Mesh versus extender sets the threshold. And if the signal is strong everywhere and the speeds are poor, this is congestion and adding radios is the wrong direction: interference.

What it gets right
+EasyMesh support means one network name and real handoff, instead of a second SSID you have to switch to manually
+The gigabit port turns it into an access point if you can run a cable to it
+AX3000 leaves enough headroom that the halved wireless throughput is still usable
What to watch for
−EasyMesh only works if your router supports it — check before you buy
−Wireless mode still splits its radio between router and device
−Costs enough that a budget mesh three-pack becomes a fair comparison

Common questions
What is the difference between an access point and a Wi-Fi extender?+−
An access point is fed by an Ethernet cable; an extender reaches the network wirelessly through your router. That single difference means the access point has no throughput penalty while a wireless extender passes on roughly half of what it receives.
Is an access point better than an extender?+−
Yes, in every measurable way, at a similar price — provided you can get a cable to it. That proviso is the entire catch. Without a cable, an extender is the only one of the two that functions.
Can I turn a Wi-Fi extender into an access point?+−
Usually, if it has an Ethernet port. Run a cable from the router, switch the device from extender mode to access point or bridge mode, and give it the same network name and password as the main network. You lose the throughput penalty entirely.
