I am constantly confused by text editors pitching themselves on speed. Is the world really full of developers going crazy with frustration because they’re waiting on vs code to do something? I opened a 100,000 line text file a few days ago & it rendered in like half a second, considering I do this about once a year it’s really more than good enough.
I think it's just that everybody has been looking for THE editor, and so it is natural that people would develop their own. I think what we're seeing is that VSCode is becoming THE editor (if it's not already there). At this point it's hard to compete. I think the biggest contender is IntelliJ, as many people really seem to enjoy it, but I would predict that it's going to be hard to fight against free.
Several times I have been on the brink of trying out spacevim for java development , out of pure frustration but the amount of config and tweaking needed scares me. I don't need much, lightning fast auto complete, auto import and Google code formatter integration. One of these weekends I'll bite the bullet I think and set it all up.
