This is all contextual, for someone else they'll say X and someone else they'll say Y, this is purely my opinion;
I only enjoyed year 12 because I made year 12 a year where I'd kick back and enjoy as a result of my efforts in year 11. If you haven't taken Year 11 seriously or you're not already ahead, I'd urge you focus more on studying.
Do I miss high school? Yes and no:
Do I miss chilling with my friends? Yes.
Do I miss having dickhead teachers? No.
Do I miss the experience of trolling said dickhead teachers with my friends and proving them wrong? No.
Did I enjoy it? Yes.
Did I miss good teachers? Yes
Did I enjoy the HSC? 100%
Does that I mean I would retake it? Never in a million years. Ask me in my next life.
Pretty much its just being nostalgic/happy the experience has happy and reminiscing over it rather than wanting/missing it. In fact this is what hypes me up more for university since its a different feel, experience, lifestyle. It feels refreshing.

I will say one thing for sure, the fun you have in year 12 will def be different to the fun you have in uni. I'm new to uni (3rd week) and the "fun" of it really comes from its flexibility, independence, exploring the city + campus w/ ur friends and so on..
(Shout out to this idiot
@temporarylol for making us run around a city for 2 hrs and getting drenched for PIZZA.)
If you decide to stay in your room 24/7, try to dip school, ignore making friends in HS - then yes, I'd say you'll have that feeling of "Fuck, maybe that extra X ATAR points I sacrificed my 2 years for wasn't worth not having a group of friends" when you don't have people to chill with after the HSC.
