10.69.2 really isn't that much better than 10.12 IMO.
It's much much better in turns and unprotected turns.
But overall, there's too many unnecessary brakes and a couple of annoying aspects that make it not comfortable / fun / safe to use compared to 10.12.
Just one example: merging behavior onto crowded highways = just tries to rush to the front, avoiding all other cars like they're obstacles, lol. Even when there's no merging lane left, it's still trying to push past the front car.
I also enjoyed the 10.12.2's general highway performance more as well.
