My favorite still is and most likely will always be the Zvex Distortron.
It's meant to sound like a cranked Marshall but it's got a 3 way sub selector that still preserves low end really well, and two gain stages (lo and hi). It's had the most flavor and presence of any other pedal I've tried after it (which is fairly extensive, as my buddy works at a guitar shop and is always bringing back new pedals to try out when the store gets them in).
Also as a word of advice, I would stay away from the TS9B, personally. I got one for $20 and don't think it was even worth that.
