By "folks like me" I meant those that place more importance on things like build quality and call quality than the average Joe. Sorry for any confusion. Besides, you don't need experience with 20 phones to judge things like that. I've had exactly four and the best build quality and reception/signal strength were on the two Moto droids I've owned. Quite frankly, it isn't even a contest.
Like I said, the S3 radios and build quality aren't terrible. But if the Droid Rzar HD and Maxx HD offers a similar UI experience as the S3 AND also provides better build/reception, it would be enough for me to consider a switch. Obviously, I'm making some assumptions based on past experience. But it's not like I'm in a rush. I'll see the phones in person when they launch and read some reviews first.
