Yeah the difference between Cleveland and Cincinnati is significant. Cleveland has culture, has unique things to do, etc. Cincinnati sort of has that but most of the city is a decaying mess of hills and old buildings. Outside of the modest downtown, there's really nothing, a lot of it looks like has been left untouched since the 60's. There's really nothing you can do in Cincinnati that you can't do in another city. I haven't been to Oakland proper, just Bay area, and I don't think you can consider it the worst of anything with SF just across the bay. Also, considering the seasons they play in, I'd throw Phoenix in there as worst cities to visit in MLB. First of off the city is a sprawled out mess with absolutely nothing distinguising it, other than the lack of grass, cacti and moutains in the distance. There are things to do, Scotsdale is nice of course, as is some of the older more established communities in Tempe, but the problem is its pure hell in the summer. It's like the inverse of a Chicago winter but with the same effect...everyone hibernates. Once you've been to Phoenix a couple of times, its really really undesirable IMO.
