Saw them in a stadium setting sometime in the last 7 years. NEVER again. Sound quality was horrendous and it was like watching a bunch of ants run around on the "stage" setup (and this was supposed to be state of the art setup - nope).
If you just want to see them for the experience, and the tickets aren't too dear, then go for it, but keep your expectations low for the music/view and maybe you'll be pleasantly surprised.
(although the concert wasn't great in terms of the acoustics, it was cool to see the Stones, and we sat next to a VERY drunk old lady that kept yelling "start me up!" all through the beginning - and then offered to get us -perfect strangers - drinks on one of her many beer stagger/runs. An there was the idiots that brought their 6-ish year old kids to the concert and then were forced to cover their eyes form most of the show due to the giant screens depicting some risque sexy stuff during the music... like the cartoon naked lady riding a giant tongue. Bet THAT was fun to try to explain later that night. So we have a few funny stories.)
