I would hold of judgement until you use it. I actually enjoyed it quite a bit as there wasn't as much of a tradeoff to booking something later.
In G+ days if you wanted an E-ticket, you were stuck not being able to book anything for 2 more hours. With LLMP, I was able to kind of Juggle E,D, and C tickets around so we were basically walking from one LL to another without any waiting or zig zagging.
Maybe I got lucky, but I actually think I prefer the new version, I actually felt like I was on my phone less because there wasn't the same urgency.
Same experience here. Even on Thanksgiving week I found it easy to use. We would usually do one park in the morning and then plan another in the evening. It was really easy to line things up and I felt like there was good value. I was skeptical of the change but it worked for us and was less stressful/time consuming than Genie+. My only complaint is Epcot. I hope tiers go away when Test Track re-opens.
