I voted "Simple", because I think you mean the rules section.
I think the rules for making a character (Stats, Level, Race, Class, etc.) should be fast, streamlined and simple. D&D 4E is much more to my taste in this regard than D&D 3E (or similar games, like Arcana Unearthed or Iron Heroes) ever was. If I have to spend more than 2 minutes comparing a feat choice it's a waste of my time. This "problem" is why I never really jumped on the 3.x bandwagon.
That said, I can spend a lot of time creating the roleplaying aspects of the character - backgrounds, motivations, personality, etc. But the nice thing about that is that you don't need to know everything up front before play; it can grow and develop organically during the campaign.
I really like 4E's balance here. Using the CB I can have a new, fairly unique character of any level up and running inside 5 minutes (depending on how quickly I can settle on equipment choices). Perfect.
