I actually used to be an avid Sublime Text coder, but at some point I switched to VSCode for other aspects of DX besides performance and my happiness with that changeover (compared to when I'd tried Atom in the past) is what convinced me that we could definitely build an Electron app that, although the perf would never be best-in-class, could definitely be good enough for 99.9% of users and use-cases. We definitely haven't optimized quite as much as the VSCode team, but not being fully optimized means I can still improve perf for our users (myself included), which I'm always happy to do!
