Have you tried UltraEdit? I used it 10 years ago, so I don't know how well it has aged, but I preferred it over Notepad++ at the time.

The reason why I don't use it now is because IntelliJ and vscode covers most of my need, and it's hard to justify the extra expense at my work place. I sometimes miss how well UltraEdit worked in multi-column mode and hex edit mode
