I'm a silencerco fan (omega, saker, others), but the last suppressor bought was a Dead Air. Dead Air's keymount is arguably one of the best, but i haven't launched a can downrange with either silencerco ASR or trifecta mounts yet. I'll be swapping out to all DA keymounts as funds allow for all the cans.

You need to decide if you want to direct thread (screw on) a can on every time or if you want a quick mount muzzle device. 2nd question is weather or not you will be getting a larger caliber rifle in the future that you want to suppress or only staying with .223/5.56. Be realistic in the goal here as that really drives the answer as to which can to get.

If you want to save money in the future, buy 3 cans now (a dedicated .22 can, .45 pistol can, and a .30 cal rifle can) and be done with it. The .45 will do all pistol calibers and the .30 will do most rifle calibers and the .22 stays on .22 because they get dirty as hell and need to be cleaned on a regular basis vs most rifle and pistol cans that are sealed/welded and cant be cleaned.
