Waf factor is important 
I tried to buy An x1 for wife and kids for video games and after almost forty minutes they were almost at the point of throwing up. It turns out we were all very sensitive to rainbows and dlp artifacts .
I would Go with 8" EM focus at the minimum with today's prices .
Ps the bad news is the X1 has higher ansi CR than those models you listed, a very important spec to know .
PSS just a CRT joke, no need to correct or to confirm !! just an harmless joke not meant to mis represent any facts .
