I've ran both, and I really prefer Tomato. DD-WRT is very nice though, but I ended up not using most of the features it offered. Tomato is very lightweight, and fits all my needs perfectly. My router is also a little buggy (really need to buy a new one) and Tomato runs with fewer dropped connections than DD-WRT. I'm sure that has much less to do with the firmware and more to do with bad hardware.
