I used a Gibbz side charger

I built kind of an oddball on a special lower. I put an adjustable gas block on a 16" .300 black out barrel with the intent of making it a straight pull bolt action for the least noise when suppressed. Then, if I want semi auto, I just have to open the gas block up the proper number of turns. I haven't shot it enough to get that dialed in, but it is pretty quiet when shut off!

I wanted a left sided charging handle so I could keep my firing hand in place and reach up and reload. I do like the feel if it and could see using one for a more standard build. It is a non reciprocating handle, so you completely lose any forward assist action, which isn't a concern to me anyways.

I'd say if you like the FAL system go with a right hand like Gunners X-Products or my Gibbz:

If you like the AK or Garland/M-14 style then go with the Stoner:
