That would actually be a tough choice. There are a lot of factors that would sway my decision.
There are very talented .cgi haxors, and there are artistic template haxors. I would also have to consider their responsiveness to querys about implementation and resolution of issues.
You have people like qasic that are obviously very talented and have a more professional approach, then you have others thay may be lacking the knowledge and experience to roll out some of the larger, more intrusive hacks but they go out of their way to answer question via whatever means possible. I would probably have to vote for qasic for the first one, with a few others being maybe a single click behind.
