You can make a pretty good electron app or one that kinda sucks. Slack is in the latter category.

VS Code (or rather VSCodium in my case) is also electron based but it's been relatively snappy in my experience - though I don't use a lot of third party plugins.

Say what you will about Microsoft but the performance of VS Code is really good.
