Yes, if it's not too late, get '98. It's a much better buy in terms of number of characters and replay value. Not to mention the way it plays (much more solid than 2000, each character is also much more deep).
I've heard mixed reports about 2001 (some people say it's great, others say it's terrible), but you can't go wrong with '98.
