Thanks for your opinion! I am also very new to /e/ and the Fairphone and have some similar thoughts.
However, coming from iOS, the Bliss launcher definitively made transitioning easier for me. It helped me getting startet.
(Nevertheless, I also switched to OpenLauncher for similar reasons as you describe).
For me it would be helpful to further learn about your experience, e.g., which apps you are using.
I had most issues with my camera, see Camera terribly slow in FP3. Is your camera working fast?
