I will input my current experience with my DNA.. except i know the thread is mainly about comparing with a samsung S3....
I am currently on vacation in the mountains of NC and the resort we stay at has always had bad coverage.. i constantly bounce between verizon 3g, extended network 3g, and some 1X.. i brought my RAZR (OG not HD) and as you can see i am having to use my razr to type this.. :-(... my dna "will" get a signal but it bounces so much that making calls or having a usable data connection is horribly sporadic but the RAZR is doing quite well.. sadly enough so is my wifes iPhone 5...
While at home both phones show almost the exact -dbm signal... but then again i live less than a mile from a cell site.. so it appears the moto does a better job of holding a weak signal... good thing i only come here once a year..
