UltraEdit is probably the best text editor there is. Not the best IDE or anything, just the best text editor. It seems thoroughly underappreciated, though, for some reason.
It's the only editor I'm aware of that can do do disk-based editing, that is you can open a file of multiple gigabytes quickly and edit it because it doesn't load the whole file into RAM.
That's quite a claim. I'd put it up against EmEditor (https://www.emeditor.com/). Not only does EmEditor have amazing support for large files, it has Excel-esque GUI support for delimited files.
I use vim out of the box with no plugins and on windows. Not sure if that makes a difference. I’m also typically not editing the file but searching logs.
