I came from nvim after using vim for decades. For me, you could approximate Zed with endless hours of tinkering in nvim, or I could just use Zed.

Things that keep me: fast. Easy project wide search that is fast. Easy file completion that is fast. Easy ability to add/remove line numbers from a gutter. Vi keys that... kinda mostly work. Sorta. Code collapsing that I didn't have to spend hours fidgeting with that also mostly works with Ruby (except for rescue clauses / end-of-function exception handling which collapses weirdly.)
