I honestly didn't find
Genie+ useful on my January trip. Individual Lightening Lanes were good, but once you got through making that reservation the Genie+ availability was already at late times for the good rides. It especially wasn't useful if you are a rope dropper like I am. You could accomplish more going early than you could with Genie. That said, I read an article about how much better it is during slower days. Well, yeah, cause less people means less demand for that, but it also means lower waits. Does that make the cost worth it then if all its saving you is 20 minutes? I think they are fully aware Genie is gaining a terrible reputation, hence the little disclaimer they now have on the page for it, which honestly won't help sales imo. Is only skipping 2-3 lines worth the $15 for the whole day? I'd rather pay the $10-$15 for the headliners individually. I wouldn't be surprised to see major changes made to Genie once they are out of the anniversary period and Epcot is back to fully functioning. Possibly going to a tier system. The level it is now, a medium price one that's more available times, and then a premium level that includes the ILL rides and repeat riding with no reservations in advance, similar to the top level express pass.
I don't have genie included for my whole trip, but I probably will add it for two days... HS where I found it worked best, and one of my MK days.
