My immediate reaction to this is “It’s early”.
GLL+ is definitely more available now because (1) the parks haven’t been that crowded, and (2) Genie + is brand new and I would guess that a lower percentage of park guests aren’t using it, either because they don’t know about it, don’t know it works, aren’t willing or able to pay extra, or don’t think it’s necessary because standby lines haven’t been that long.
As crowds and standby lines grow, and more people decide there is value in Genie+, we might find that it will be difficult to get as much mileage out of Genie+ as we can today. Those “free” 3 scheduled FPs for headliner attractions at times we chose might look pretty good.
But, in the meantime, I intend to take full advantage of it.
The other thing to consider is that Disney may have a threshold of people who use it before they decide to increase they daily fee to keep LL's available and the lines moving.
