Since I upgraded from 7 years old budget LCD... This is bright (turned down as much as I could), fast (well 1ms), sharp.
I do not see 144Hz, but definitely can see 60Hz. Maybe placebo, but feels better. PC can not keep all games with ultra settings@144Hz, so there can be opions what are you going to favour more.
Monitor is simple, classic, sits on old VESA mount, old DVI cable sticked in (check that your DVI is "full"(?) or "double"(?) to get 144Hz out).
Excellent monitor, but I have not used anything new and available competitors are 7+ years old. Technologies have improved since then, can see it with unarmed eye (or whatever that saying is).
