I have a friend that is looking to switch to VZ. She's looking for a phone for free or close to it. I narrowed it down to the M-8, G3, S5, or the 2nd gen MotoX. She doesn't need it to do anything special. So which one do you recommend? Or which one should she avoid? I'm a fan of Moto because of their radios and I love my 1st gen X.
