Nah, I am not cool enough to go brake less. I can get to a stop pretty quickly by alternating legs and locking the rear wheel though. But down steep hills and in traffic, I prefer to have a brake.

I really like the idea of using own strength and leverage to power/stop the bike as much as possible. It feels more organic to me. So I tend to lay off the brake as much as I can, which means if I see the opportunity to skid in a non-******y way, I usually take it, even though I know I can stop faster with my hand brake.
