[Q] UK - Which Note 4 topic

I want to buy a Note 4 Unlocked. But as is normal it appears these days its Rip Off Britain so wanted to avoid the UK one from UK stores and would like to get the 64bit chip version. Anyway there are so many note 4 models I don't know which will be compatible with UK networks. Would the N910C be OK here and if so are there any other I could look at?

Thanks n advance
