Getting my daughter a Galaxy S5 for a graduation gift. It will be unlocked and used with a Straight Talk AT&T SIM. My question is whether the "H" Model or the "F" model is the better one or is it a toss-up? There seems to be a small price difference. She is not interested in LTE capabilities, is NOT a power user and has no intention of rooting/flashing. Any input on the pros and/or cons of these 2 would be appreciated. thanks!
