I half agree with you, but I suppose that depends on the context. It's true in that they're both frameworks for their respective languages - but where most people that think of Ruby automatically think of Rails, the same is not true of PHP and Laravel because of all the alternatives (CakePHP, CodeIgniter, Yii, et al).
I'd also go so far as to say that Laravel and Rails have different ways of solving problems, so while Rails is everything-including-the-kitchen-sink, with the (supposed) Rails Way being king, Laravel takes more of a skeletal approach, providing a solid framework with few bells and whistles, onto which you can craft whatever you need.
It is my hope that Lotus, a new Ruby framework currently in beta, is taking note of what Laravel is doing, and will follow suit.
Anyway, sorry for that massive off topic turn.
