Episodes 15-17 are complete filler, which is not a criticism in itself, but nothing very important happens in these. You may enjoy it, only you can decide.
As for episodes 18-24... if you've watched all of SAO I and SAO II up to this point, then I would definitely recommend just finishing the series. These episodes... I believe the less said about them, the better. I thought they were very good and that it wouldn't be worth it to spoil anything about them to any potential viewers. This is the sort of thing where you're better just not knowing anything going in to them. But I will say two things:
I really like Sword Art Online. And I even like Kirito
but he's a terrible character for all the reasons you mentioned and more. There's something about that which I find endearing, it's hard to explain. Kirito shows up in every episode in the series, but he's practically a secondary character in this final arc, so if you're sick of him or at least his Gary Stu-like perfection, you're in for a treat!
Also, the casual misogyny of both SAO I and SAO II always felt unnervingly creepy to me. The rape scenes didn't flow out of the plot and felt tacked on simply to titillate viewers. (Don't believe me? Look at how well those scenes are animated! It's like you're there!) Thankfully, there's no more of that to be found here, either.
If you're a fan of SAO, just watch it. It's one of the better conclusions to any series I've watched in a long time.
