I only keep sublime text around for opening +500mb dumps, everything else was moved to vscode years ago.

Anything more than 500mb and I switch to less for instant reading/searching and sed for instant find/replace.

Absolutely. I actually just made my own syntax for highlighting the log files in Laravel (Monolog): https://github.com/james2doyle/sublime-log-syntax

VSCode is just as fast for opening 4 GB log files

It is not just about the opening, it is about the searching. Vim is fantastique, although VSCode got faster over time too. Grep is fantastic too (I am not trying to out-hardcore here ... I mean specifically for log file searching not actual coding!). Splunk is better though, but sometimes you are local, and sometimes you don't have a few mill to burn.

Vim is not slower!

I agree and I do use Vim for all quick edits I need. Just wanted to challenge the idea that Sublime Text was better than alternatives in the space of GUI text editors
