TCH decided to standardize their server farm to one Cpanel theme (rather than many). This was done to make support from their end easier IIRC (instead of supporting multiple themes with multiple potential fixes to multiple problems, they settle for one). TCH is currently evaluating a theme that better suits users and will be transitioning to it. Also, they had problems with other themes when it came to adding Fantastico and things of that nature. Unfortunately in the business world you have to make decisions like this. Not everyone can always be happy.
Meanwhile, I've been on Cpanel X theme on all my accounts here since I started, and have become very used to it. That doesn't mean I need the "dumb-down and pretty-up" to be able to get my work done (personally I prefer the command line to the GUI in 99% of situations), however I've grown used to it (as I said).
