After reading that article, I think the answer is that LTE is the better long term technology but its not there yet.
You've got to ask yourself the question - how long do you expect this phone to last? If six months to a year then just go an buy one. If you intend it as a long term purchase, wait 8-10 months and see what the next version release brings.
This doesn't look like a finished product to me: wait until a 4-core LTE version arrives (assuming that LTE is in the planning pipeline where you want to travel)
