Well, I can tell you few reasons why I am still using (and will use) Sublime:

- it is way faster to start than, for example, Visual Studio Code and I just prefer it for quick edits (at the same time it is easier to configure than gVim/Emacs and has modern UI) - I like the way multi-select works in general and in the vintage mode specifically (I'm very productive with it) - I use it heavily when I need to analyze source code - the indexer is fast and allows me to quickly jumps between symbols and files

It does not mean I use Sublime solely. When I need to develop some code in Python/PowerShell/Go/C#/... I switch to Visual Studio Code, where I have all the necessary plugins and debuggers. About a year ago, I turned to Sublime from gVim (which I have used for more than three years) and never looked back.
