I can’t really compare them because I’ve not used LineageOS, but I got a Fairphone Gen6 with /e/OS a few weeks ago and it’s better than I expected.
One of the problems with custom roms is you have to unlock the bootloader to install them which can then prevent some apps from working. I didn’t have a problem with that because the phone came with /e/OS pre-installed with the bootloader locked. Depending on what you need the phone to do it might be worth considering. It gets quite frequent updates.
The main issue I had with /e/OS was the launcher was too basic for my needs. However, this was easily fixed by just installing a different one. Most of the default apps are good enough that I haven’t needed to find a replacement for them.

I understand what you’re saying, but as long as they keep operating in the same way while gaining users it’s better for everyone. More users means more privacy because it gets harder to tell traffic from different users apart.
