Asking me to say what I like best seems limiting, considering that there is so much to like. Among my favorites, though, are the amazingly fast full-text searching of files matching a mask across entire directory trees containing thousands of files, and the ability to use regular expressions in replacements almost exactly as I once did in Perl. The tight integration with UltraCompare, which is simply the best diff program ever, is also handy. I use both together to solve even the most complex source control merge conflicts. Throw in huge file support, spot-on syntax highlighting, ability to feed the active file into external programs or shell scripts, mass indenting and outdenting, brace matching, … you get the gist.

It's not on everybody else's radar, e. g., Sublime Text gets regular mention, along with all the freebies like Notepad++. I wish that I saw UltraEdit on those lists from time to time. Review collected by and hosted on G2.com.
