I think that will be more subjective now then it ever was before. Really depends on what you are looking for in style, finish in the end.
I agree the S&W looks nice, and the talk of the smooth action seems like a great bonus. In the Winchester models you can find it in a take down version in 16" barrels, the henry X with a 17" synthetic stock, or the standard 20" barrels with the other wood, stainless looks are great as well. Henry seems to be the leader in after market stocks, but I imagine the others will soon follow. Ruger is now making the 45-70 with the updated tactical style stock, but yet to offer in the 44, but I imagine will come eventually.
I'll be watching the S&W and the henry Supreme, as I have been wanting to add a 223 to the safe, and the supreme just seems to be a nice fit for that.
Soooo, really depends on what you want it to do in the end and overall look.
