Storm, I started to write a response and I realized that you are probably asking a rhetorical question. If you are not, I would be happy to provide an answer.
Here is my subjective experiences:
Miller Park (love eating at Fridays in left field before the game; good beer; beautiful architecture)
Angels Stadium (I love the Angels!; and it is a safe place; rock outfield is cheesy)
ATT (I like it's location; and I like the right field seats)
Wrigley (for the history and fan's enthusiasm)
Qualcom (Old Padre's stadium; caught a foul ball and seats felt like you were right next to the action).
The Jake (Good pubs around the field; neat outfield walls; but getting run-down)
US Cellular (It was more clean than I thought it was going to be?)
Anaheim Stadium (I love the Angels!; but the pre-rennovated football stadium was cookie-cutter bad)
Chavez Ravine (old in 1991; ancient now)
Old Oakland Stadium (5$ bleacher seats were pretty cool to see the hated A's when they were good in the 1980s; plus you were just as close to the action in the bleachers as you were on the 1st or 3rd base sidelines)
Al Davis's Football Oakland Stadium (embarrassing).
