Well, my phone just experienced SDS and living in the US, it seems near impossible to get anything done about it. So that's something to consider. I need a new phone now, and it will likely not be another international device after this experience.
LG G2 on AT&T - Best phone I've used to date.
Note II N7100 - loved it, a little big but finally gave me the battery life I needed from a phone..but it died of SDS
Nexus 4 - couldn't get over poor battery
Galaxy Nexus - loved it
Nexus S - tried for a month, meh
Nexus One - loved it
