I have a Pantech Verizon phone. I absolutely Despise it to the point of no return. The sensitivity is terrible on it, you cannot calibrate it, and when you press a button it does not recognize it, and presses another button on the opposite side of the screen. It is absolutely trash.
I have a Razr Maxx and I can't say enough about the battery in this phone, I'm not really a power user but I can easily get away with 2 full days of moderate use without charging.
I have the Samsung Galaxy Y DUOS(Dual sim). It's not the best phone but really helps me with its dual SIM function
For the record it still uses android 2.3
