What would you pick? Straight Talk or Prepaid Verizon?

My boyfriend currently has straight talk, but its one of the cheaper phones and that flip open and close. We both agree the web sucks. I love being able to get on Google or Facebook, but the internet on the cheaper phones are terrible. I seen a touch screen that I really liked for both Straight Talk and Prepaid Verizon, at WalMart. It was definitely more pricey, but I want to know if the interent is better. Like a regular smart phone. I don't want to pay 100+ for a cool touch screen phone and come to find out the internet is crappy, just like the cheaper phones. Anyone know if the touch screens have better internet? And what is better, straight talk or Prepaid Verizon?? I would really appreciate it! Thank you so much! :)
