Unbranded phones do not contain any carrier specific software and when updates are released they get them straight away from HTC's servers.
In the UK unbranded handsets typically come from the likes of Carphone Warehouse and I also think O2 provide unbranded handsets (though I may be wrong on that last point).
If you can get un-branded then do, as you'll get updates a lot faster and it wont be filled with the carriers software and changes, which often you have no chance of removing unless you root and install a custom ROM.
