I have the Marlin (.357 mag). It is simple, accurate, and fun. I too was in debate. I finally asked my gunsmith, and he suggested the Marlin. The Winchester has the historical appeal though. He suggested Marlin due to the better construction, better machine work, better accuracy, and better price (I still secretly want a Winchester). He was correct. Marlin's are nice. I don't think you'll be disappointed by any of the three though. I am looking for a pre-64 Winchester, and will get it as soon as I find one in the price range I can afford.
The cross-bolt safety sucks. Last deer season, it cost me a great buck. I had him in my sights, within 25 yards. I pulled the trigger, and a loud metalic click scared him off. I'm a firearms safety fanatic, and in addition to using the half-cock safety, I opted to use the cross-bolt too. The moral of the story is that if you use a cross-bolt, don't forget to disengage it prior to taking your deer!
