I've used both Rails and Laravel in production, and while I equally love both, the amount of hassles you face with rails in prod is an order of magnitude more.
That's not a fair comparison though. For any non-trivial app, most people deploy PHP using a CGI, PHP-FPM being the standard. Even the cheap, shared hosts provide FastCGI these days.
That being said, getting RoR or Django up and running is really no more difficult than getting Laravel setup and running via PHP-FPM.
