Yes, BTTF2 was a visual tour de force! It's still amazing today! I would love to get my hands on one of those models! And of course there was the pioneering Vista Glide camera that ILM made that allowed the same actor to appear as different characters or different versions of characters in the same scene without a static camera or a very obvious matte break. Genius!

The only thing that bugs me is that, on the DVD, I can see the garbage matte of Biff's Pleasure Paradise. Don't get me wrong! I don't want it removed! Of course, I don't have to worry about Zemeckis doing that, thankfully. But it's one of those things that you can go your whole life without noticing, and then, when it just pops out at you one day, you can never not notice it!
