UK mobile Wi-Fi

I have had mobile wi-fi on a 24month contract on three. I live in the south-west where there is no LTE yet.

However the HSDPA speeds on my previous mobile wi-fi reached around 18mps consistently where I live.

Now my contract is up, is it worth renewing my three contract (getting the new mi-fi along with it) or switching to EE?

I plan to go to university next year, everywhere I have applied EE says they have planned 2014 LTE coverage (as does three).

Is it worth getting the LTE enabled mi-fi now or getting the faster three mi-fi, which will only support 3G+?
