In terms of referencing, the thing that made PF1 worth it for my group was the combination of resources like the PRD and d20pfsrd. Especially the latter, with the hyperlinks built into the site, so that, for example, you could very quickly and very easily navigate to lay on hands, or manipulate, and no searching / flipping through was necessary. This streamlined the complex and in depth system to a point where playing it was easy and fun. I think the problem with PF2 is its young age. Once the rules are finalized, and once 3rd party sites start to compile all of the new stuff, I think the game is going to be a much better (and clearer) for everybody.
