I own both a marlin 1894c (357) and an M1 carbine (30 carbine). Although both a lot of fun, the most versatile is certainly the marlin, and if you reload or have 357 handguns, its definitely the best choice.
38 special loads in the marlin are GREAT for plinking. 357 loads can easily be used for close range hunting. Since I have several revolvers chambered for 357, its a no brainer for me.
BTW, with the right load (mine being 5.1 of W231 with 125 grain JHP bullet), the marlin has better than average 50 yard groups (1.5 - 2 inch groups with iron sights off a bench)
Either way, you can't go wrong in the fun department!!!
