I like the more traditional "older feeling" ballparks too but I don't have a problem with Chase at all. It's different, pretty unique, and serves its purpose. I haven't been to many of the retro ballparks but they all seem pretty nice. The only one I guess would be the New Busch Stadium and I loved it. It had an unbelieveable classic feel to it yet it has all of the modern things a stadium needs these days. I'm going to Rangers Ballpark next week, so I will see how it compares.
So far, Chase is probably my favorite I've been to, New Busch may barely beat it out.
Overall, without actually visiting all 30 ballparks, I'd say my top 5 would have to be SBC Park (Giants), PNC Park (Pirates), Fenway Park (Red Sox), Wrigley Field (Cubs), Camden Yards (Orioles).
I'd put Chase somewhere in the top 15 or so. It's not among the best, but as I've said before, it's on par with most other stadiums.
