I agree that someone who hasn't used the particular toolset is a poor choice of critic.

Having used both RoR and Drupal, I think that the answer depends on what your goal is. I've had to price out projects in both, and the costs are usually similar. The timeframes are usually similar. So, given that the results, timeframes, and costs will be similar, the end result comes down to personal choice, like with anything else.

People knocking down other people's choices is bad karma, and speaks more about the individual making the criticisms.
