I’ve tested both frameworks, with one public result (built with Mojolicious), and another one ongoing (playing with Dancer).
I like both, but both frameworks have their own problems.
Mojo it’s more advanced than Dancer, but it has an important problem with the documentation (the lack of it) and with the non existent API stability (at least when I tried it, it was easy to break your application after an upgrade).
Dancer it’s simpler to use (and simpler overall), with good and almost complete documentation, but it’s less mature IMHO (and you can find rough edges while programming a real world application).
Anyway, both are interesting projects and I recommend them if you want to try a modern Perl based MVC framework.
