In general I'd agree, although I personally prefer buying my badge online and getting it mailed to me, so I can just walk in on Thursday without having to deal with lines. If you can arrive in time for the Wednesday pick-up, it's not too bad, but DO NOT try to pick up your badge on Thursday, unless you want to spend most of the day waiting in line. I would also add that the convention center is nuts when the con opens each day, but if you show up a half hour later, you can usually just walk right in.
