Thank you for your interest in the Husqvarna blowers.
The difference is generational, the 350 is a slightly updated version of the 150 series of blower.
Since these two blowers are essentially the same I would buy the one that you like the best, there were only a few minor differences and mostly cosmetic and I believe the blower nozzle opening on one of them is smaller ( increased speed ).
