Nearly all my kit is Makita. Corded and cordless. I personally don't think it's all that, but once you have bought a few cordless tools, you are kind of committed because if you stick to the one make you can buy 'bare' units which are cheaper.
I have about 6 different cordless Makita tools, one charger and four batteries. Which means carrying less stuff on site.
There corded stuff is all middle of the road too. If (god forbid) the van got broken into I would probably start again with Milwaukee as people seem to sing their praises.
