No doubt about it, @Raj Singh 
I'm counting on that!

I vote for VSCode for the one major reason, I am a macOS user tired of carrying a VM for Studio. Other than that, I love how light and versatile VSCode is and so far I have a really great experience playing around with InterSystem IRIS/Docker/GitHub, and before I could even notice I am easily 90% of the time there.

Having said that, I am yet to see VSCode getting close to Studio in terms of features, which is still deep in my heart. For that reason my VM still follows me around.

I rather not talk about Atelier as I really did not enjoy the experience.

Haven't tested but I would guess yes, I will run some tests changing the version in Dockerfile and post the outcome here.
