note 4 in UK which is ok? topic

So I am thinking of getting a note 4 but in the UK it's the F version but I was thinking the C version looks better...snappier and possible better functionality with lollipop later? Is C the only other safe model in the UK? I see it seems to be the only one with the same features for connectivity.
Also would I need to do anything to the phone to use it in the UK? Anyway would be good to hear from anyone already using a note 4 in England etc.....Thanks.
Oh and also wondering if any other models are ok...
