If you have ambition and have the potential to get into a nice school, then going to community college is ackin to shooting yourself in the foot. Sure, you can still have a nice career afterwards, but you're cutting yourself from many more opportunities you would have had otherwise.
"excellent instructors" depends purely on luck wherever you end up to, and pretending they are automatically better in CC is deception. Most importantly, how bright are your classmates is the #1 thing that drives higher achievement in my experience, as the learning material is all over the internet anyway.
I would like to add that in the sort of signalling game that higher education is, making "rational" bets such as "taking a year to get partying out of your system" is very much inferior to just doing what is deemed socially acceptable (which is partying while in college).
