I have used both, and the Charge seems to be more for moving Apple people to Android. I say this because the app tray is horizontally scrolling unlike most other UI implementations, and ALL of the icons are the Apple-style rounded squares with an image on them -- the Charge also really likes to accentuate colors on the display. It's also made of more plastic than metal, so to me it feels cheaply made vs the Thunderbolt. The Charge also has physical buttons in contrast to the capacitive buttons of the Thunderbolt. I also noticed that the Charge lags quite a bit more in the UI than the Thunderbolt does. Your best bet is to cart your ass over to the Verizon store and play with the ones they have on display and get the one you like more. Also, if you don't live in a 4G market you might as well look into getting the Droid X2 instead because it's faster with its dual core processor.
