I have owned two model 41's, both 1980's guns. One with the short 5.5 heavy barrel, one with the longer barrel (7 inch?). Maybe 4 Ruger mark ll's, including a couple heavy barrel target guns, and a High Standard Victor.
In my opinion, the Rugers are very nice, and close to the other two brands. Most shooters can not shoot up the Rugers potential. That said, the S&W and HS are usually a little more accurate, with much better triggers. In serious competition, they are the guns to beat.
A lot has to do with how the gun feels and balances in your hand as well. You should try each if possible, and see what you like. Aftermarket grips, barrel weights and lengths can also make a difference. So can using a good quality, consistent target grade ammo the gun likes.
Price is another factor. Rugers are what, about $400.00? A clean model 41 is more like $750 or more. A Victor, maybe $600 or so for an original CT made gun.
Right now, I own a Ruger MKll 5.5 heavy barrel with a 2x scope that is very accurate, and has accounted for a lot of small game. I also still have the Victor, as it is so accurate, with such a great trigger. I always shot it just a little better than I did my 41's.
