They're all going to have the same features, unless you're talking about unnecessary addon bloatware(Gpu Tweak, Aorus Engine, Dragon Center, etc).
How about this: Which one offers the more/most satisfactory CS experience in your area, in case something goes wrong with it?
The best warranty service is the one you never have to use, but - you know, just in case.
