I hate ScITE with a passion.

For windows, I recommend Notepad++, its not WYSIWYG though. But its an awesome text editor with syntax hilighting, file format selection (macOS format, DOS format, Unix format - all use different line ends), block collapsing...

For Linux, I use gVIM, but its worth noting that all VIM based editors have a steep learning curve, but once learned, they are brutally powerful.
