How many teething troubles did the Mk7 have?
Not as many as you would normally expect... from memory the main problem were dealers not removing the transit stops from the suspension!
I'd probably take a punt on a Mk8, but suspect that I won't get a chance with the timings of my new car cycle.... probably a Mk7.5 again for me. Yes, I'm THAT happy with my Golf's that I'd have a third Mk7 variant in a row...
