In my experience, it depends on the band and the venue. Indoor venues are a lot harder to get the bass resonance right. I don't think I've ever had bad sound (for whatever style of music was being performed) at an outdoor venue. One band I saw at both an indoor and outdoor venue. At the indoor venue, the sound was a constant woom-woom of bass resonance from the kick drum, with the snare poking through. At the outdoor venue, I was able to hear all the instruments well balanced with one another.

Don't forget the impact a good sound person has. My best experiences have usually been small indoor shows with a passionate local sound guy that knows the venues well.
