I don't think my X runs any faster, but with SetCPU and AutoKiller (not ATK), I do go to bed at midnight with 20 to 40% battery left, where I was having to recharge around 4 or 5 PM before running those root apps. I can also run Titanium Backup now to get a complete phone/apps/settings backup, which I wasn't able to do before rooting.
Forgot to mention...I didn't delete any of the bloatware. What's the point? You've got more than enough memory on this phone.
