Currently all my big bores are H&R, 3 45-70 of which two are the standard version & one Buffalo Classic which is an absolute dream to shoot.
I had a Marlin lever but traded it towards a S&W 617, I see another one (guide gun) somewhere in my future eventually.
I don't care much for the SASS stuff so I probably won't worry much about type versus performance.
Buffalo Classic, I'm in the market for one, and I've heard nothing but good things about them!
