I feel almost exactly the opposite of you. After my son was born, I feel like we get way more out of Disney and have been going more and more. Yeah the crowds can be pretty brutal and sometimes there are some grumpy times, but we all love going to Disney. It is a bit pricey, but we know our way around, how to work everything, and how to just chill and not rush (which is the biggest deal). I used to feel like we always had to plan ahead and rush around especially back before FP+ when I had to run to get our paper fast passes. Now with FP+, we can see what all is open and be surprised if a big ride opens up. The only real big downsides in my opinion are the Child Swap and Security are vastly superior at Universal.
At this point in my life, I really don't care much for Universal. I feel like they are charging too much, I have had a nightmare of a time with paying for our passes, the crowds are insane, and the rides that they are building don't interest me. Add on top that there is almost absolutely nothing at Universal that my son can do other than Barney (maybe he can do Kang and Kodos now?), it just doesn't seem worth the hassle. It also felt like we were walking around a lot more trying to find a ride to ride because of the wait times and the app being consistently incorrect.
It's amazing how much one's perspective can change in a relatively short time frame. I have been die hard Universal since 98, now that Disney has finally woken up it makes me remember why I loved it so much as a child.
