I'm not a lever action expert or guru, but have handled the new S&W, Marlins, Rossis and Henrys. They all seemed like quality guns to me. I've had a Winchester 30-30 and Marlin .44 for years, and recently acquired two Henry .357 carbines. Even though both of mine are the shorter barrel versions, no way around it, the Henrys are heavier than the others. Especially the one with the octagonal barrel. Can't say the Henrys are better than some others, but can say they seem to be good rifles so far. One of the Henrys, with the semi-buckhorn rear sight, shot so high at 25 yards as to be all but unusable. I called Henry about it and explained the issue. The nice lady at Henry said she would send me their tallest front sight at N/C. She did, and that fixed the issue.
I've read that some .357 lever actions balk at feeding .38 Spcl. ammo, but both of mine fed the several types of factory .38 Spcl. I've tried just fine. That's about the sum total of my knowledge about the new lever actions..
