Fellow ST4 user checking in. It does everything VSCode does (minus remote development, which I don't need) with 1/4 of the resource usage. Just a quality piece of software that I'll keep using for as long as I can.
There are dozens of us! Though for serious work I'll sometimes reluctantly switch to VSCode due to Sublimes language integrations always feeling hacked on.
And lately Sublime has been mysteriously freezing and crashing my other programs (though it might be Windows' fault, unclear) so I've reluctantly started developing my own editor...
I also paid for ST3, but I switched to ST4 for the hardware accelerated rendering. I don't like their licensing policy anymore, so I just dismiss the purchase signs. I want to get my company to pay for it because paying 100 USD _again_ is just absurd for me.
I have no plans to switch off though. This is still a heck of a lot faster than the alternatives
