Well it depends on what you mainly use your phone for. If you text a lot, then you should definitely get the EnV2. People I have talked to that have that phone really like it. The only thing is, one of my friends who has it, the whole front of the phone doesnt work at all, so she has to open the phone up to do everything because the entire front side is totally useless. But of course this can be prevented. If you arent planning on texting that much, you should get the Dare. Its a really cool phone and touch screen phones are really in right now. If I had to choose between the two of them, I would personally choose the EnV2.
Hope this helps! Good luck!
