Both are great options. I am not sure where you heard that python has a bad MySQL provider or that Ruby is difficult to deploy. Even though those are opinions, I would highly disagree with both. I have worked with Rails (ruby), Django (python), Pylons (python), and now Pyramid (python). It really is a matter of opinion. You will find much more information about Rails and it is easier to get started with, but I have found that after a couple hours on a Rails project I am fighting Rails more than it is helping me. So it is a highly opinionated topic, but I personally prefer Python using the Pyramid framework. It does have a higher learning curve, but to me it is worth it.
