I was using LineageOS with microG before installing /e/, and the experience is almost the same, in better.
The installation is a lot easier and microG is already configured, you just have to add the apps you want and that’s it!
Just one thing if you want to keep your message, you need to copy them to Signal and do a backup before.
Bliss Launcher is great, maybe an option to sort automatically apps should be nice.
And for multimedia apps, I suggest to use Vanilla Music for music player (add the support of replay gain), and VLC for video player.
