There is no best one. Each person has different tastes and thus what one person likes the other will hate.
Some prefer eye candy, others prefer enhancements, and others prefer just basics. It's impossible to tailor to everyone's tastes. The best one can do is give the player options so they can tailor to their taste as much as possible.
I don't have any flash in mine. To call it utilitarian would be one way to describe it. But I prefer content over flash. There are better ways to use memory than by wasting it with flash and pretty pictures. Your video card only has so much memory - and that memory is better served rendering 3D models and textures vice 2D flash
