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). For long haul international, if I can't fly in business, I'm adding my vote to an exit row seat in E+. Another bonus that hasn't been mentioned is if the flight isn't too full you might have a chance of having a seat open next to you in E+. Obviously you need to get lucky, but in premium plus you're almost guaranteed a full cabin since people try to upgrade themselves in various ways. I'd personally take a window seat in an exit row with the middle seat empty over premium plus for a long flight (just make sure to dress warm since many of the exit doors aren't insulated that well and it can get cold).
