A PRO would probably have Milwaukee or Porter Cable, then Dewalt, then Makita, then Ridgid.
Ridgid has a reputation for GREAT hand tools and I suspect will make a huge bid to bring their power tool line up to that standard.
As far as Cordless, and this is MY opinion:
First and second are Porter Cable and Dewalt. Which is best depends upon the cordless tool. Makita who used to OWN that market, has fallen way behind in the last 5-10 years.
Milwaukee has recently introduced the V28 line which is powered by LiIon cells which are touted to be both lighter and stronger than the NiMh powered lines from Dewalt and PorterCable. I haven't played with them yet so no reports.
Hope that helps!!
