Strawbery-Perl++. I got fed up with AS perl PPMS and collisions between compiled things from them vs. Randys Theoryx PPM (although, Randy has always been very helpful, and got me through some noasty how-to compile issues with AxKit/libxml/libxslt and their Perl cousins).
Strawberry Perl has been an utter joy to work with on windows so far, with only a few modules not compiling completely. If it weren't for testing with my older perl installs, I would have banished AS perl from my machines long ago.
Now, if someone would just fix Dango::Socket on win32 perl... :-)
