Based on a bunch of different brands I've owned I'd chose HTC first, Moto second, Samsung next to last and LG dead last.
Why? I've had hearing problems with most Samsung phones, not with any other brand. Their sound systems seem weak. I can't hear 'em ring and I can't hear the caller.
LG...... I got a new one a year back, couldn't configure my email. VZW said LG blocked my ISP, hard to believe so..... I called LG, the customer disservice person said, "Yes, we block that ISP." Me, "WHY?, nobody else does?" LG, said.... basically, "We just do, so live with it." I took the phone back and I'll never own another LG product. I could have sworn I was talking to AT&T disservice!
PS, I really don't want a Nexus phone.
