I liked Atom, performance was tolerable on my overpowered machine, but MS killing it just sent me back to Vim and modernizing my plugins.
Zed positives: Metal rendering. I use a Mac, so one platform's fine. But negatives: Rust, so I can't/won't touch any internals, and I loathe the Rustacean propaganda wing. No extensions yet. Config is another stupid json file.
You know what's great about vimrc? It's easy to put in a few config commands, and then you realize you're working in the scripting language. You don't have to switch to a whole new file format. Thanks, Bram.
