Perl5's CPAN is still very useful, the language is still available on most UNIX systems, it has some really nice OO modules like Moose, and the community still has lots of conferences and releases regular updates. I personally prefer Python in this space though.
Perl6 on the other hand is gorgeous. You can write beautiful OO, FP, imperative...whatever code. Grammars and MOP are great. The parallel support is cool and the Unicode support is top notch. You can also do really cool stuff not normally seen in scripting languages like restrict the type going into a function to be a non-negative integer in the range of 1..10 kind of like in Ada. The downside is that the language is still immature and adoption is slow. The VM is getting better, but with things like Nim, Julia, Crystal(fast languages), Perl6 is a tougher sell.
