And I completely disagree about JetBrains products being more integrated. Some integrations are MUCH better and deeper in VSCode. To give three recent examples I came across: Vue, React and Svelte. WebStorm doesn't even have some features offered by VSCode, like typechecking in templates. Not to mention that, at least to me, VSCode is significantly lighter than WebStorm and runs much faster in older laptops.
VSCode is also significantly faster and much much lighter than the ultra-integrated and native Visual Studio, so there's also that. I know because I use both, and I know which one locks up all the time and takes 40GB of disk. Seems like they just didn't use the optimisation opportunities.
Either way, this discussion doesn't seem to be going anywhere. There's doesn't seem to be anything for us to learn here. I'm addressing every new single point you make, while you keep moving the goalposts by cherry-picking my posts while ignoring the parts I cover :/
We started this discussion by saying "it would be awesome if X existed" to which you said "100% disagree". Sounds like you don't want me to have some tools, or maybe you're under the assumption that my desire is for Unity/Unreal/Godot to stop existing, which is definitely not the case.
