the 026 is a tried and true workhorse parts are easily accessible it is a pro class saw that is easy to maintain and work on. the 346xp (new edition) is a 14,500 rpm speed demon that loves a steady diet of <18" wood it wakes right up and cuts as long as you spool her up. If i was looking for a great limbing saw I would grab the 346 if I was looking for a single saw the 026 would get the nod PSSSST I like torque and the 346 is all about horsepower lean on her a bit and she drops out of her rpm sweet spot if you need to throw a 20" bar on a saw stick to the 026 if 18 is ok and you don;t mind the whine of a 346 then you will get more done quicker that way. Ohhhh yea if you like cleaning air filters stick to the 026 if not the 346.
