This is high praise coming from an Emacs user :) I also formerly used Emacs with much joy, but I'm even happier with Zed now.

Zed has a lot of issues in flight; maybe these are useful to you? Here are the issues that have been filed under the label "area:parity/emacs". Some also have the label "state:needs repro" (needs reproduction). I wonder if any of them scratch your itch? Weighing in might help get your pain points resolved a bit faster?
