Re: I considered these..
I fitted my house out with Unifi gear (a couple of UAP-AC-PROs and USG-3), along with a Draytek 130 VDSL modem. Not necessarily the cheapest products available, but utterly worth it IMHO.
Full, strong coverage throughout the house and garden, and the only issue I've had in the past 18 months was with IPv6, and that's because I had misconfigured it.
