I'll have to think on this one for a bit...
It's a difficult call. Both monumental records of equal import. At the end of the day, I always go with what I listen too more.
Floyd and I have always had a difficult relationship since I'm not a YUGE prog rock guy.
I'm not a prog rock guy either, really. I like a little Yes and ELP. DSOTM and the two albums after that are pretty accessible and easy on the ear compared to most prog though.
I think i have to go with Jimi anyways. They both amaze me when I'm able to hear from a fresh perspective as opposed to someone who's already listened hundreds of times. I think Experienced just amazes me a little more.
