I'm slower to adapt, slower to change, and slower to make a decision. I also decided to migrate Canon to Sony. But I'm giving myself 6-18 months to really decide.
Admittedly, this means I'm kind of crippling the Sony as I will have just a few native lenses and otherwise I'll be adapting. But this is because one of my drivers is that I'm expecting to be out of the sports shooting game in 18 months, and I'm not really gung-ho to learn a new system and shoot sports with it too.
As I see it, it took me a long time to go from fair to good at shooting sports, and some chunk of that is my comfort in using Canon. I'd not be comfortable in assessing a wholesale change too quickly because the new gear will always be at a disadvantage due to my own ineptitude with it.
So I don't have great advice for you. My own path is different, but I guess I do caution to watch out for the difference between "the camera does this" and "I don't know how to make the camera to this."
So far I'm seeing that in situations I understand, the Sony can be very good. It also sometimes makes me crazy when I can't figure out a setting or don't know how to get it to do something. I think there is a nuance to the AF. Like....the Sony is super flexible and has great software. But it also acts like the AF sensors (despite having 600+ sensor locations) are not cross sensitive and so in some ways worse than Canon. That (IMO) is why it hunts in situations where (to me) it seems like it should not. That's the kind of detail that you can only learn by using and trying.
For now I still own the vast majority of my Canon stuff. I also have to fight off the urge to accelerate the move. Bonus was really good at work this year, and with a spring trip coming up I was super tempted to get a FE 24-70 GM or FE 24-105 G OSS. But why? The stuff I'll be shooting on this trip is landscapes, and the Canon 24-70/2.8 II is going to be perfect for that adapted. So I held off.
