Quality content is important, and lack of it is a reason to quit a service for sure.
I haven't had any issues with the service of Disney+, so they're at least doing good enough (on my devices, on my home network).
On the other side of the spectrum, Apple TV on my devices takes about 8 attempts to start a stream, including a reboot. They would have to have a big exclusive that I really wanted to see for me to use that again.
Smallish differences in how long it takes to get a stream started (including browse/search time) probably drive long term behavior, when content quality is similar enough though; because I'll tend to use the service that gets me into watching something I'll enjoy sooner; and when the same content is available on multiple services, I use the one that's faster to get started.
