I have a Motorola V60i now, but LG is going to be stepping back up to the plate next time around.
I've had 3 Densos (Sprint's old Touchpoints), and an LG-TM510 (Verizon, that LG was like $150 when the V60c was $399).
I also have a Nokia 6360 for AT&T (TDMA) that my GF carries for emergencies and one minute "I'll be late," or "I'll see you in a minute" calls. It's currently on the ECallPlus.com (an AT&T reseller) prepaid plan. That Nokia 6360 is a good phone, but I haven't been as impressed with other Nokias.
I voted Motorola, since that's my everyday-carry phone.
