Interested in a Milwaukee myself now.
I had the Makita, great bit of kit but I sold it last year.
The one problem I did have with mine was the locking pin was a spring pin and the socket would come off pretty regularly especially when stripping which was a right ball ache to be fair.
How does the socket lock on the Milwaukees??
Try makita btw251z it has a retaining pin so the socket is held in place a lot better
