They both have they're pros and cons! However, Sense blows Touchwiz 3.0 out of the water...And the build quality of the TB is just better over all...if you drop it with the case on your good...The Charge is lite as a feather (which I like) but if you drop it, case or not, its a problem. As for for the In the hand feeling...TB wins, I have em both, and the TB feels better in the hand IMO.
However, when u start talking about screens...the convo goes south. Nothing is as good as a Samsung screen IMO,,,NOTHING AT ALL. Yes the TB screen is really nice...but the charge screen is just plain beautiful. And yes the battery is better, not lite years better, but better in every day use.
So which wins....Neither IMO!
Both are good, but are running with last years technology.
Give me a dual core, with Gingerbread 3.0, a sick screen, good battery life, and 4G LTE...
Phones like the one I just described will be available within 2/3 months...And at that point both my Charge and TB will be on eBay waiting to get sold.
