in reply to Constructive thoughts on Dancer2 v Mojolicious

I worked for many years with an on-line store system that was built using CGI::Application and it worked just fine. Booked hundreds of thousands of dollars in sales every month without a hitch. Both of the frameworks that you mention have plenty of success stories, so, really, it just comes down to your preference. Take a few days to build-out a small subset of your project in each of them and see which one feels better to your sensibilities. You're not going to "make a wrong decision" either way.
