The best steel coaster I have been on I would say Millenium Force-Cedar Point. This ride is very quick going up the lift hill and is not bumpy at all.
The best wood coaster I have been on would be Raging Wolf Bobs at Geuaga Lake. Now this ride is a little bumpy..but I love the feeling you get when you sit in the very back. Now you haven't experience anything like this ride when you sit in the very back seat right hand side. Yes the side makes a difference. Make sure you don't tighten your seatbelt too much. Just make sure your lapbar is down all the way. You will literally be standing going down the 1st hill and the new retracked hill.
The best overall coaster would have to be between Steel Venom(Geauga Lake) and Wicked Twister(Cedar Point). Now I still need to ride in the front of wicked twister..who knows I might like it better than Venom. What I love about Steel Venom is the stop on the second time going up the second spike. You literally slide out of your seat. You haven't lived until you have ridden in the front seat.
The long answer is that "best" topics are frowned upon on CoasterBuzz, so don't be upset if this topic gets locked or deleted. It's all in the TOS that you agreed to when you sign up, so make sure you take another good look at it -- not only does it lay down the general ground rules, it gives you a good idea on how to keep the quality of discussion as high as it is around here.
That said, welcome to CoasterBuzz, and any sour grapes from this little spiel were unintended. :)
Secondly, what is with this place lately? Has their been an internet boom of stupid conversation? ;)
Read "The World is Flat" to learn about the internet boom. Very good book. :)

Best Wood Coaster I've Ridden -- Tremors, Silverwood Theme Park
Second, and I want you to know I'm not trying to be mean, but "best" type topics are frowned upon here. In fact it is in the Terms of Service you agreed to when signing up here:
4. Unacceptable topics of discussion:
...If your topic has any word ending in "-est," think twice about posting it.
So Ellen don't be surprised if your topic is closed or deleted. Don't let that discourage you from posting here, OK? ;)
Used to be, every September you could rely on the "Freshman flood" to the newsgroups. Every fall, like clockwork, a new batch of kids would start college and discover this wonderful thing called the Internet. They'd all go running out, screaming and babbling like, well, kids. Eventually some of them would go away, while others would learn the ropes and then in subsequent years dread the flood with all the other seasoned users. For me, Freshman year was 1988, at CMU :)
Nowadays, with the huge number of ISPs and people signing on all the time, there's no set flood time anymore, but the phenomenon is much the same. For hobbies like this one, there IS a basic "start of season", but it's not September anymore...
At any rate, as others have said, this kind of topic has been done to death. Sorry...
