Visual Studio Code is extremely promising, and at some point may become my primary editor. However, it is still VERY early in the preview stage. There's no plugin system yet (so no Vim mode, or other things that people often find essential).
Also, while free-as-in-beer, its licensing status is currently proprietary... a significant turn-off for the audience that Microsoft is targeting with this. Every rumor suggests that they'll be open-sourcing it eventually, and that the process just takes awhile to work its way through legal, since Visual Studio Code borrows its editor code from their commercial Visual Studio Online product. But it's still an open question.
Overall, I am "intrigued-and-cautiously-optimistic" right now (its startup time and responsiveness are MUCH faster than Atom's!), but I'm not ready to switch over full time just yet. I'm looking forward to seeing where they are with it by early next year, when all of the other cross-platform .NET stuff is ready for general availability.
They use the underlying core, but the code is their own. One benefit I see is that Microsoft gets to provide bugfixes to Electron that Github may find useful. As well as Microsoft may just end up porting some of their products (Office) based on their experience learned by developing for multiple platforms.
