RegexKit. Without a doubt.

I use it in about 75% of my projects.
RegexKit is very nice and extremely comprehensive, but it has quite
a large footprint and is probably overkill for many uses.
Unfortunately, RegexKit Lite (the stripped-down version) uses the
built-in ICU library which uses a syntax quite different to the
PCRE that most people are used to.
Since the goal in both ICU and PCRE is to be broadly compatible with
Perl regular expression syntax, I think it's an exaggeration to say
that the syntax is "quite different". There are things in PCRE that
aren't supported in ICU, and vice-versa. And neither of them
support everything that is implemented in Perl (partly because you'd
have to actually *implement* Perl to do it).
NSPredicate anyone?
The MATCHES operator uses ICU's Regular Expressions package.
