Honestly, I don't know that I could do what I want to do with just one rifle.
My class/SHTF AR SBR isn't designed to shoot fast for competition at long ranges, but my multi-gun AR isn't designed for CQB, running suppressed, reliability across ammo, and getting dirty. If you forced me to choose, it'd probably be the multi-gun rifle (because the Vortex Razor GenIII is, uh, expensive), but I might screw around with it slightly (eg, put on an ASR brake and some offset BUIS).
