My experience is that the overall Sublime packages are much more stable and do not need so much rework and maintenance. I cannot even count how many times Atom packages failed (maybe it's also just because I cannot see fancy failing error messages of packages in Sublime).

I think that's really a side effect of it being free. (And I wonder if VSCode will eat that ecosystem...)

Do you have examples where the Atom/VSCode package is much better maintained than the ST3 one?
