I'm not sure what your carrier situation is there, but in my not-so-humble opinion there is no way I would sacrifice LTE for $100. When the Nexus 4 came out, I sacrificed LTE for it and saved about $300 over another competing phone and it still wasn't worth it for me due to the difference in HSPA+ and LTE around here in California. That's just my situation and yours might be different, but I'll add a heavy vote for going with the LTE model. I do not think you'll be sorry.
Then again, I've always been good at helping people spend their money
