I've never had trouble learning a new system, and we've been visiting about every 2 years. Before our last visit (August 2023), I spent weeks carefully researching G+ so I'd be facile with it.
Nonetheless, with G+, we hit a wall. We hated using it on the days we bought it (burying my nose in my phone all day, pounding the app, constantly jockeying for more convenient G+ times or trying to find a random reservation for an otherwise "sold out" attraction, instead of enjoying my vacation), and we hated not having it on the days we didn't buy it (and getting constantly shunted aside in lines in favor of G+/
DAS guests, which is demoralizing and makes you feel like a second-class citizen by the hundredth time -- conversely, when we did have G+, we felt like entitled d*&$#-bags passing all those people in standby).
While we felt that all the previous systems (FP, FP+, or the standby-only-plus-some-VQ during COVID) were fairly egalitarian and helped to make our trip objectively better or easier to plan ahead of time, the very existence of G+ made this last trip objectively worse for my family, in the areas that matter most to them: ride access, short waits, and the ability to relax and just enjoy being in the moment. For the first time since we started taking the kids in 2012, we came back from WDW with a bad taste in our mouths, and made no plan to come back in 2 years (or ever), until Disney puts something better in place.
