Unfortunate that you're being downvoted because the slow start time of VS code is honestly such a big blocker that it outweighs most of these features for me. I just can't wait 10 seconds every single time I want to take a note.
I am on a fairly RAM constrained workstation (4GB) so I have no choice but to close it when I'm not using it. Otherwise I'll spend just as long swapping as I would opening a new instance.
I've seen some people make the argument that they want to use their editor for quick edits to single files, which is a fine use-case. However, VS Code is really not designed to be optimized for that case. It's really about editing code (hence the name) as opposed to quick edits to configs, etc.
It's usually best if one knows a few different tools designed for different scenarios. Right tool for the job.
At the same time though, it is purposely not positioned to replace a full-blown IDE. So what is the use case that it's optimized for? Why does it offer to add an "open with code" context menu item to every file if it's not expected that you'll be using it for quick edits on individual files?
It's not so much a professional issue as a personal one. When I get an idea and want to start taking some notes, a 10 second delay is more than enough time for me to get side-tracked by the details. So I skip VS code and open notepad instead, in the interest of getting the idea out as soon as possible. And as the complexity of the project starts to increase to the point where VS code's more advanced functionality might actually come in useful, there just never seems to be a good time to stop what I'm doing and change editors.
Mechanical disks are basically free in this day and age, so that's still a pretty significant savings over an SSD which is more like the price of a mechanical disk 10 years ago. You could cheap out and do a small SSD/large HDD combination, but I find that having an excessively small system drive is nothing but headaches, especially for software development where you are frequently installing different toolchains, etc. Until I can afford an SSD that is comfortably in excess of my storage requirements, then I'll stick with the HDD.
I've been using both lately. VSCode for when I'm working on a project and the editor ends up staying open all day. I also often have to work with large files, so I use Sublime to pop them open and make a quick change.
