I prefer this breakdown. Yes, a T6 bonus in the 4th slot is enticing, but honestly can see myself using 2 or 3 slots of these on builds. I'd have to sit down in Mids for a bit with the final updates to see if I might ever 4 slot a travel power with one of these, regardless of which breakdown you use. But my gut feeling is that I wouldn't, even with the T6 bonus unless, perhaps, it was a T6 bonus to HP, Defense, Resist, or Recharge and I doubt that would happen.
