First, I should state that it's really not about the language, it's about the coder. You can build great and crappy things with any language. And every language has it's warts.
That said, the best language I've used in the past 20 years of programming has got to be Modern Perl. Not the chicken scratch Perl you saw 5 or 10 years ago, but Modern Perl. Here are some of the strengths of modern Perl:
It's object system: https://metacpan.org/module/Moose
It's web frameworks, especially Dancer: https://metacpan.org/module/Dancer
It's ORM: https://metacpan.org/module/DBIx::Class
It's package installer: https://metacpan.org/module/App::cpanminus
And so much more. Do yourself a favor and at least have a look at Perl.
