Best Rom for Sensation XE topic

Hi All,
Just want a bit of advise.
I have been using my old Sensation XE as my work phone for a while now, but would like to put a custom ROM on it.
At the moment it is standard, and think it could do with being updated.

Also do any of the ROM's allow you to use the built in buttons on the XE?

I have put the ZOMBI-X ROM on my Asus Transformer and have been impressed with that, so any advise would be appreciated.

Thanks in advance
