The 357xp is as close as you get to the MS361 in the Husky model lineup.
Stated power output of the 357xp is .1 kw lower than the 361 in the US, and .2 kW in the rest of the world (it is the 361s that are rated different, not the 357s). I think you would be hard pressed to notice the differense.....
The 359 should not be in the same ballpark when stock, but nevertheless a much better choise than the 455.
The 357xp and 359 is slightly heavier than the 361 according to the independent test reports that I have seen, even though Husky claimes the opposite.
I doubt if you will notice that difference either.
The ergonomics are quite different, imo there are pluses and minuses with both models.
