Reviews are a dime a dozen, authoritative ones are somewhat harder to find.
Following is a definitely non-authoritative one, for what it is worth.
Are the mikrotk access point so good or not ?
It depends. 
Do you want to spend sleepless nights studying and experimenting because you believe (wrongly) that your home network needs an uber-complex setup including VRRP, VRFs, VLANs, etc,?
Or more simply you need something particular that other brands OS doesn’t offer?
Go for Mikrotik.
Do you want to install an AP with 10-15 clicks, in a simple, normal, network?
Go for TP-LINK, netgear or the like.
From a pure “wi-fi coverage” viewpoint, there is not a definite answer, there are highly contrasting reports, from people very happy about their Mikrotiks to people that throw them in the bin and get another brand after having experienced every kind of limited connectivity via wi-fi.
Personally I would have no doubts in choosing a Mikrotik as a router or (managed) switch[1] (including using the rather powerful hap Ax2 and hap Ax3 as such), as an access point I would have some doubts[2].
The good thing with such Mikrotik devices is that they can be re-used in other setups, in different roles, so if you are looking for the best bang for the buck, Mikrotik is definitely a good choice.
[1] should I actually need one, I am very (maybe too much) old school, but for my simple needs (and slow speeds) el-cheapo, unmanaged ones have been enough for me.
[2] in my perverted mind an AP should be an AP, a simple AP, I don’t need it to be also a router and a switch, with an overwhelmingly complex configuration, but as said some Mikrotik devices are very versatile, and can be re-used, unlike other brands “pure” AP’s, still the latter ones are much easier to setup, JFYI:
