I have had Fein for more than 20 yrs and they are bomb proof. And the most recent one i bought some 5 years ago is the more powerful unit. If i was to buy a new machine it would be the Festo as i think the attachments are very well thought out. Basically someone has seen some things the Fein needed but weren't addressed. But i really think the Fein is very hard to beat for just being a tough dependable tool.
