What are the best Markdown editors for Linux?

Allegedly, Visual Studio Code is "lightweight". Yet, running multiple instances of it at once, you may get many "out of memory" messages from Windows despite 16 GB RAM. (While of course also running other things. The point is the comparison with some other IDEs/editors where running them alongside the same number of other applications doesn't cause Windows to run out of memory). This is mainly due to the Electron base.
