We use both depending on the situation. VS Code is more modern and certainly better for Git and Merge tools than Studio but it doesn't have all the abilities of Studio that I've found, global storage properties etc. We've found VS Code doesn't handle physical files as well as Studio at least for InterSystems so its unfriendly when using CSPs that are version controlled.
That sounds quite hopeful, do they communicate between each other out of interest?
At present, each namespace is an entirely separate self contained system. We'd like each to better represent being like the live setup so that apps in development and testing environments behave how they would when going live if you see what I mean. Maybe a scaled down test would be the best approach to see if it has any major problems.
