My limited experience with Festool is that their tools are first class.
I have not used their jigsaw, but an acquaintance of mine has. He says
the dust collection on it is just amazing.
I have used the Bosch, albeit a 20-year old, and found the old barrel
grip much better that the new barrel grip.
I bought the Milwaukee. I just love that thing. Good price too.
Made in Germany...go figgur.
