Everyone has their individual likes and dislikes. My wife had the Samsung Epic while I had the HTC EVO 4G, and she traded in her phone for the EVO after she used mine. I hated the Samsung Epic. Touchwiz seemed very clunky compared to Sesne. Since then, I have remained loyal to HTC and stuck with, what I feel, is the better of the two manufacturers. I feel HTC makes a better product and provides better support. My brother has the Epic 4G Touch and likes it a lot but says the battery life sucks. I love everything about the EVO 4G LTE. I have never been one to swap out batteries, so the non-removable battery is not an issue for me. I have never run out of juice before bed time, where it gets plugged in and charged over night. If you are on the fence then I would recomend using the phone once they are available in the stores to see which one you like better. I don't think I would move away from HTC at this point, even if I tried the S3 and liked it better. I have faith that HTC will fix the issues and feel that the HW will last me until the next gen of HTC phones are ready for my consumption!
