Guys this is supposed to be a contest with simple rules, I'd say be glad that we even get a chance to influence the type of logo. I think wether or not you want a stylish logo or not is entirely a matter of taste. There are plenty of examples of great logos who are not abstract at all, so that's not a real argument unless it's based upon your taste. (Psygnosis, Raven Software, Adobe Photoshop, Fishtank Interactive (to bad it's no more) just to name a few have great logos). A banner-like splash screen usually is a lot more graphic than a normal logo by the way, so it's moreso the otherway around if you ask me.

Cheers
