Painted VS coated break rotors?

So I've bagged some nice new wheels as old ones were buckled and corroded badly. Issue is that the new ones show off the breaks and callipers quite a bit. I do need a new set of rotors and I was wondering what your takes on painted vs coated rotors are? From what I gather the coated *seem* to be longer lasting (In terms of rusting up by the vents and the centre hub) vs the painted. What do you all say?

My two choices are painted TRW for around £70 for the pair or Coated Zimmermanns for an extra £15 or so.
