You are right! I should not have posted the first hit of my search for a comparison. I shouldn't have compared here at all, but simply linked to Sublime Text.
The thing is: Sublime Text fits perfectly my needs. I had a very short look on BBEdit a couple of years ago, but I didn’t get the feeling of "Yes—this is my tool".
I like Sublime’s syntax coloring for many programming languages. And the way RegEx is implemented is what I appreciate most. And I often use it for changing the Encoding of text files.
