My understanding is that Text::CSV is just a wrapper for Text::CSV_XS now so no need for people to worry about which one to use. If you are on a platform that makes XS modules difficult to install then you can install the pure Perl version and let Text::CSV fall back to that. The advantage is that using Text::CSV makes your program more portable.

DESCRIPTION

Text::CSV is a thin wrapper for Text::CSV_XS-compatible modules now. All the backend modules provide facilities for the composition and decomposition of comma-separated values. Text::CSV uses Text::CSV_XS by default, and when Text::CSV_XS is not available, falls back on Text::CSV_PP, which is bundled in the same distribution as this module.
