I would go with Tomato unless you want customizability. Last time I checked, DD-WRT was just a set of packages on top of OpenWRT, so going with straight OpenWRT lets you add only the functionality you need and customize everything to your heart's content. I would choose that route over DD-WRT. However, I did run into some reliability issues, (wireless connections would drop spontaneously every few weeks) which show up in DD-WRT as well. In OpenWRT, many basic settings (all settings unless you install a web interface) are only accessible via config files. That can get tiring. Tomato is rock-solid and dead-easy to configure, but startlingly light on functionality compared to *WRT. If you have the time, try them both!
