You definitely should. I obviously voted derek, because my life revolves around his music. I would have to say that I almost like everyone of them equally the same, as they have their own strengths. Derek rockin the slide (my weakness), John is the master of jamming (Crossroads anyone?), Warren just does his own thing and it always rocks, and then Doyle... I just love his style. Not to mention he has an incredible voice. You should most certaintly check out the Arc Angels and Smokestack. There are a lot of awesome tracks to be heard.
