You may not hear this from others, but I would NOT switch your phone OS and desktop OS at the same time. Assuming you live a digital life there is just TOO MUCH to have to deal with while dealing with tbe hassle of things that don’t make sense, or require you to stop what you’re doing and google the answer.
I love /e/OS and would absolutely recommend it, but there are just shortcomings that slow me down all the time (are you OK with the play store compatibility suddenly stopping and you cant download apps - do you wait and see if it starts working after a few minutes? reboot your phone? Log out and back into your google account? Switch to/from anonymous? This happens more than I think folks would readily admit and the solution is just different each time)
Once you are up and running fot a few weeks with whatever change you want to make first then sure go for the other one.
Best of luck!
Once I had to start running daemon-reload on changing freaking /etc/fstab I was done with systemd. Give me any other init system at this point.
