I wouldn't say any one particular brand "dominates" my tool collection. I've got such a broad assortment of different manufacturers in my bags and boxes.

Sockets: Stanley chrome, Grey Pneumatic duo sockets 3/8", Sunex 1/2" impacts, ATD torx master set, ATD hex master set.
Pliers: Channellock, Knipex, Wiha, Proto long reach needle nose, Crescent double-x long reach needle nose, and NWS.

The wife has a 26" 3 drawer Husky intermediate chest that she has set-up to keep all of her nail polish & stuff in...looks pretty good how she did it!
Hmmm...so that's somewhat of a break-down off the top of my head that I can remember at the moment. At some point, I seriously need to take some up-to-date pictures for the toolbox and tool cart threads.
