The one that I've not yet seen in an alternative is a simple way to implement simple custom syntax highlighting. Npp has the UDL GUI, but I don't even need the GUI if specifying what to highlight and how to highlight it is as straightforward as the UDL XMLs are. Sadly most things have either hardcoded syntax highlighting or poorly documented convoluted specification files. Most of the other features I use most are fairly common though: line sorting and dedupe, column editing, regex search and replace, EoL conversion, compare/diff, etc.
