And some great features inherited from Visual Studio.

Peek definition. when you want to peek a few lines of a method or type, you don't have to go away from the current position. In Sublime and Atom, it really bothers to open another tab.

Navigation through overloaded methods.

When a text editor is built to help people coding easily and make itself extended easily, it has to include some basic infrastructure so that extensions can focus on their specific implementations.VSC does this well, it is not only a text editor, but also have a skeleton of an IDE, and left all other things to extensions.

Out of the box (which matters - just because an extension exists, doesn't mean everyone who would benefit from it can find it, add it, configure it, etc.)?

For one, nice git integration. You can see lines added/changed/removed in the gutter, unobtrusively.

Sublime has a plugin that does something similar but it's not out of box and it's not as nice/polished.

This is just one thing.

The cool telemetry phone home features that cannot be turned off in a reliable way (think updates). It's the feel good vibe that runs through all new MS apps and Win10. We should thank the third CEO for his great vision and be happy to give him all insight he needs. He is clearly steering his thriving platform to the next level.

My main one is the top-notch TypeScript experience.

it's actively developed.
