Samsung S3 LTE and Note II LTE off the top of my head.
NOTE: Many phones have multiple variants, eg. 3G and 4G LTE models, and then the LTE model may have different versions for the different networks.
Personally I'd opt for a mifi device, and an external battery pack to extend its mobile life, then you can pick and choose the best phones based on other features like screen/apps etc
LTE while more advanced in other countries is still very much a catch up game for the handset manufacturers, i.e. while UK is late we are still only just seeing the handsets appear anywhere in the world.
