New setup time

I have a problem id like some suggestions if possible.

Running fibreX gig and im over the stability and crap Wifi at my house. Currently running Mikrotik HeX to 2 old routers as access points Linksys 120N and a TP-Link WR941ND. These are terrible together and the Mikrotik is crashing when loaded up with multiple devices.

So im looking at either going all in one - Preferred

Netgear NightHawk X6 R8000 $260

Or just an access point and go back to using pfsense which does waste power.

Ubiquiti UAP-AC-PRO $290

Or has anyone got better ideas?
