I'm 6'5", and I'm not a big fan of the premium plus seat. Like others have said, the footrest is awkward and basically useless, and once someone reclines it gets fairly claustrophobic (at least for the non-bulkhead seats; I've never been in a bulkhead premium plus seat).
This makes all the difference. The bulkhead seats are the way to go. I`m 6'4" and found that to be true across multiple airlines.
When faced with the choice of exit row in Y or (bulkhead in) PE - for me, it's PE every time. The Premium Plus seat is much wider (18,7"compared to 17,1" for the E+ seat), plus the fixed armrests of the exit row seats make this uncomfortable for such a long flight even though I`m not a wide-bodied person.
