Not as optimized as the 17 with a +2. That 17 becomes an 18 with a half feat at level 4. And the +2 isn't as optimized as a race with +2 and racial abilities that match the class.And if you are Standard Array, you can get your 16 win just that +1.
Is that optimized?
If someone really wants to number crunch, you can eek out little bonuses here and there, which don't mean nearly as much in 5e as they did in say 3e. I used to have to watch out for power gaming during 3e(my favorite edition), as it could unbalance things, but I don't even care in 5e. It's just not a big deal.
