I really enjoy my Marlin .357 1894 CSS, easily one of my favourite guns.
It isn't as smooth cycling as my GF's Chiappa .44 or my dad's Henry, but as torontogungal pointed out if I got off my lazy butt and spent some time polishing the internals I'm sure it could be improved..
Loading the Henry's mag isn't as quick as the side loading gate on the others and gets irritating quickly to me, but doesn't seem to bother my dad so maybe I just need to chill.
One bonus of the Marlin is the side eject; I added XS sight system's rail and peep combo (same as the one that came on my 1895SBL) and a Leupold ultralight 2.5x fixed power scope on quick detach leupold rings. Some people don't agree with putting a scope on a lever gun, but I rarely shoot it with irons now even though it's a 30 sec job to switch back/forth. Also it doesn't negatively affect the weight too badly.
I'll try to hack my way through posting a picture of it..
