Isn’t betterbird just thunderbird with some very minor adjustments?

Its more than a soft fork but barely, like they didnt apply a few commits that removed a feature.

I don’t recall exactly.

I tried it but it wasn’t very compelling.

Thunderbird is fine. Email sucks.

edit:

this is the feature comparisson: https://www.betterbird.eu/#featuretable

They are calling it a soft fork because it does closely track upstream releases.
