I recently used G+ once on a trip and really didn't like it, never bought it again. At least with old fast pass you could pick out everything you want to ride and not have to worry about it. I don't like that it's a whatever is available system, certain rides would have required me to wait like 4+ hours, which just wasn't worth it. It's kind of insane people are buying Genie+ because I don't see the value in it. Mind you, I was even traveling solo, but to constantly have to try and methodically plan where to go just isn't worth it.
It's sad stand by lines are so inflated, when I went to TDR in May (before the 40th anniversary fast pass thing was introduced) it felt like heaven. I only waited like 30 minutes for a majority of rides, and even more popular ones had maybe an hour wait. Of course, the rides you paid for had the longest lines, but I was able to do everything in one day. I'm not sure I could say the same for WDW, I was waiting like 1 hour+ for most rides. Worst was getting in line and then finding out I was in line for 30 minutes or an hour than they stated at the beginning.
