I use it and like it a lot (but then again, I'm admittedly biased - work for MSFT ).. I use VS Code for a lot of other non-mysensors and non-Arduino (i.e. python, node, etc) development, so it's nice to have that all consolidated in one dev tool.
It's far from a perfect tool, no doubt, but a good start. Mostly I'm just happy to get Intellisense!
