The 1900, etc are fine as long as you are wired into the router. If you want to use Wifi avoid them! The hardware is decent, but the closed firmware is buggy, abandoned, and will give you extremely high latency under certain conditions. e.g. How to write a meaningful mt76 lag bug? - #16 by dana44 shows hundreds of ms latency with one of that family of devices.
If you want low latency you need something running ath9k, mt76, or ath10k. The best choice today is likely the ath10k powered r7800. You can then look into AQL and further tweeks like the ath10k-ct small buffers firmware.
The mt76 is a big umbrella, but apparently the newer mt7615 stuff is decent while the older mt7603 2.4GHz is buggy on current releases.
