Well it appears you've analyzed it pretty well. Guess you'll just have to make your decision. Would you be in a situation where you could/would move to a base somewhere? I was in a situation where I was looking for a regional and was unwilling to relocate. It does limit options. I picked PSA because I think they had the best "package" but your situation may not be the same.
Sometimes, when faced with a similar decision, I actually make a list with the pros/cons for each option next to each other. Leave that lay for a while and keep adding to it as you think of new things that matter to you.
