I have a woz rr with 7.5v boards and never had any issues in 5 years or more of buying it nib. It’s difficult, but so amazing once you open the code up and get into it. I’ll never beat it. I also have a Metallica, and I play Metallica a ton more than my Woz, but when I do play my Woz, I leave it thinking holy crap, that’s an amazing game.
As far as toy story, I waited years for this game, and am hugely disappointed. I can’t wait to try it, and decide what I think after that, but right now I had to cancel my order until I see more. The code does concern me, especially at this price point. It looks too easy and beatable, and I’m afraid of that at this point.
If you go with a Woz, yeah the 2.0 boards are ideal, but the 7.5v are pretty reliable and even Lloyd said the 7.5 boards should be fine. I was able to get an entire backup set of fully working 7.5 boards just in case for only $250 from a guy that did the conversion to 2.0. Like the other poster said before, play everything before you buy and make your own decision.
