I'm not knowledgeable enough to be able to recommend one language over another for specific reasons. That said, from what I've gathered on reading more informed opinions on the matter, it is largely just that--opinion.

Many people prefer one language over another. Both core languages, Ruby and Python, have excellent documentation and resources online as well as strong communities around them.

My comment was speaking more specifically to the case of Sinatra vs. RoR. I feel like RoR simply has many more high-quality resources available on it than Sinatra does. This is likely due to how much more development occurs in RoR vs. Sinatra (pure speculation there).
