Great thing about JetBrains is they work out of the box unlike vim where you need to spend a whole month customizing just to get back on working on the project with 20 random plugins out there and it's still probably only 30% as good as JetBrain's.
VSCode is being developed rapidly and I see many good plugins but it's still quite far behind except for the launch speed. At least it could be seen as a competitor to make sure JetBrains will keep innovating and keep the performance of their IDE sane not to lose customers to VSCode.
