I had two large frame .357 8 shot revolvers with comps, I still have my S&W 627 V-comp with a removable comp with a 5" barrel, I also had a Taurus 608 4" with factory porting. Both are large steel frame guns, and I can't really say how will they work to keeping recoil down because of the weight, but shooting .38s is very mild almost like shooting a .22, and ..357s are pretty tame too, but they are fairly heavy guns unlike a Glock.
That's all I can contribute except, I'm not sure they are much louder (I guess they are, and can't really say, but I double up on hearing protection), or they have any more flash.
My lighter aluminum S&W 327 8 shot .357 R8 M&P that doesn't have any form of comp's, has about twice the perceived recoil, but is very manageable.
