Great question. For me it feels faster (anecdotally) and certain TUI components don’t break. It also is probably my bias of loving his work as well as everyone at work using it. Hive mentality I suppose.
My experience is similar. Stuff doesn't break and it feels extremely snappy. I've switched to Zed for the same reason. I came to realize that I work much better with faster, simpler software, even if it's missing some nice-to-haves. It feels like you're closer to the problem you're trying to solve.
