+1 on the Thunderbolt, though currently it’s not in my arsenal. It’s a good phone ( like the Sprint Evo).
Atrix is alright.
FWIW: i’m currently using all carriers right now…Imho, Verizon/Sprint have really good data networks…Contrary, to others say about ATT, I haven’t had too much trouble with ATT or TMobile….
My preference would be verizon>sprint>tmobile>ATT if it was only about speed/performance. For me though, I need to have phones with a sim card… I also need phones that are rooted, and preferably one that can build an entire system image from either Google git’s repository or cyanogenmod… Hence, my arsenal
Nexus S’s on ATT, Nexus S on T-Mobile, Samsung Galaxy Tab with with a Verizion 4G/LTE personal hotspot, and there’s a Nexus One that isn’t featured…There was also a Sony Xeria Play that I got at Google IO.. It wasn’t a very good phone imho, so it’s gone.
