I don't know if anyone else brought this up but you really want to avoid the RemLins. When Remington bought Marlin in 08 or thereabouts there were tons of quality issues for a year or 2.
Don't buy used ones... from 08-12 but new Remlins are good to go. I bought 2 within the last year and they are decent and shoot well.
They are also cheaper than the rape prices that many used JM guns want to fetch and come with a full warranty. The 336C I just bought I got for slightly more than 400 bucks brand new in box.
It really had nice walnut on it too. Someone on here wanted north of 500 for a JM gun and I'm glad I bought the Remlin, it actually has nicer wood. Saved myself over a 100 bucks and lot of travel time and headache.
I bought an 1895 22 inch barrel, again on sale NIB for less than 450.00 and the wood, fit and finish on that is fantastic. I'm real glad I didn't overpay for dinged up used JM.
The word is getting out and the prices on both of these guns at the same supplier has jumped back up well over what I got them for.
The wood finish on these new Marlins is bare bones and subdued, no shine, put some oil on it though and it looks just like a lever gun finish should. I also love the subdued tan kickpad, it looks nice. I'd rather a buttplate on a lever, but that's a nice feature. I wish henry would do the same and not put the thick black kickpad on its steel guns.
Henry's are a step up in metal finish and action feel, but the wood is a step down in feature, they put very plain walnut on the Henry's unless it's a special type gun. There is certainly nothing wrong with a Henry though, great guns.
I think right now the .357 Marlins are around 600 bucks new, so realistically at that its a wash between a Henry and a Marlin, depending on what you want. Henry's can be had for 600 and change, Marlins a little less brand new.
The tube feed is overrated, and really not a big deal, honestly I like it for pistol caliber. For quick follow up shots with either style, I'm just throwing a round in the open chamber, so it matters little to me.
