Just seen this topic mention three parks I've been to relatively recently, so thought I'd register to mention my opinions.
First off - Six Flags America. I went in 2011, on an American road trip with my wife (we're from the UK). We went to SFGAdv, CP, SFGAm, SFAm and BGW (and Water Country USA, if that counts). SFAm was not our favourite park of the five, but also not our least favourite park either. We saw it as kind of a smaller park with a smaller budget than the others - in our UK terms, like a Lightwater Valley (if the other parks were Alton Towers). It still had some decent stuff - Joker's Jinx, Batwing and Superman were decent, and the other coasters passable. Not too busy, half-decent weather (it rained in the morning, but being from the UK we expect that anyway - if it doesn't rain over here we wonder if something's wrong). Shame about the food (wanted to go to a specific place but it was shut so had to have burgers and fries). This was just before Skull Mountain closed, which was a fair enough water ride.
I think a lot of people probably aren't keen on SFAm as it's probably not the best in the chain - I know the other two Six Flags parks we did seemed to have a bigger budget, more theming etc. I don't know the finances and whether SFAm can actually perform better on it's budget.
Oh, and the high-fiving? Please stop it. It makes me cringe. And Joker's Jinx guy? I saw what you were scratching. Your hand is warm and moist. Please don't attempt to high-five me with that hand.
BGW - yep, I will agree with a previous poster and say it IS overrated. In my opinion, of course. This was, for us, the worst park of the road trip (not counting Water Country USA, which has taken over from Ferrari World for us as Hell On Earth). Griffon - poor Sheikra clone. Alpengeist - don't actually recall this, which shows how interesting I must have found it. DarKastle - boring. Loch Ness Monster - boring too, with the chain link loop being only interesting when viewed off-ride. Apollo's Chariot was pretty good though, but one coaster a park does not make. Verbolten wasn't open back then so can't comment on that. The theming was excellent though and I can quite easily see why it wins "prettiest park" awards all the time. The price, however, was HUGE - a lot more than any other park on the trip. We decided to buy a two-day pass in advance so we could come back the next day, but managed everything that looked half-decent quite quickly and then decided that queues were too big, so left early. Water Country USA the next day (which was included in the ticket) was also packed, and hell to get around because of being barefoot and the immensely painful ground.
BGT - better. A lot better. One of our favourite Florida parks (though I'm unsure whether to count Florida parks alongside a lot of others, as they're more about theming than anything else), it's got three pretty cool coasters (Montu, Kumba and Sheikra) that we frequent. Cheetah Hunt isn't bad. It's not especially good either... it's just sort of... there. Gwazi is one we go on once to say we've done it, and I hear that it's closing which is a shame - I think it may actually be good if they managed to make it not feel as rickety. Only bad experience we've had at BGT was at Zagora Cafe where they got my wife's meal wrong and lost mine, but prepared me a replacement (well, I swapped with my wife and she ordered hers again).
