all i can really tell you about a 346xp is it weighs the same as my 350, its built better, revs higher and has more power, so say my dealer, who has always been very straight with me to the point of talking me out of buying saws, and i _love_ my 350, it was a trade for a notch and drop i did like 3 years ago, homeowner hadnt even run one tank through it when i got it, ive run the hell out of it, and aside from one of the motor mounts stripping out, which is apparently a common problem that husky has brass inserts to repair, and the wire for my kill switch breaking once ive had no problems with it and i run the piss out of it
it pulls my 18" bar and aggressive chain through any wood like a hot knife through butter
come time i need to replace it im getting a 346xp
ive never liked the 36 and the new 441 is anything but impressive, the 460 is almost twice the saw without being noticeably heavier
