What exactly are you looking for in a UI?
There are any number of very different ones depending on what you want. I suggest you try several and see what appeals to you, and what does not.
Some people like elegant, beautiful artwork incorporated into their UI.
Some people like a very functional UI that strips away unnecessary ornamentation.
Some people insist on certain specific features in their UI. And of course, two players seldom agree on WHICH features they want.
Skim through the Featured Interfaces, Mix and Match, and Complete Sets folders of the downloads section and look at all the preview screenshots.

Or, of course, you could cut to the chase and go to
the UI I put together and save steps.
