I don't have any experience using overdrive pedals, but a couple general distortion suggestions:
If you use Ableton, you should definitely check out their Amp plugin. That thing is all over all of my productions, definitely my favorite distortion unit. They actually have a stock Overdrive plugin, as well as a Saturation stock plugin which are both pretty nice.
Other than that, I really like Predatohm. Beware if you want to use it in stereo mode though, it can cause some nasty phasing issues if summed back to mono later on.
iZotope Trash 2 is popular and pretty good, it's flexible and has some nice multi-band capabilities.
