You'll have to elaborate, just saying "this is better" is useless.
On the other hand Perl 5 is faster for normal usage, and has mature library support, while perl6 has to catchup a lot. Perl 5 is only slower with their not-existing/silly object systems (Moose), there Perl 6 is much better.
Many perl5 devs just don't want to learn a new language yet.
Syntax: It explicitly deviates from perl6 and could have looked much cleaner.
