This was an interesting post, and I'm sure the op didn't mean any of it as a "flame". Problem is, on a lot of the comparisons, the op just said "I won't get into this, but I prefer Python" (or Ruby, depending on the feature). Those kinds of statements don't really advance anyone's knowledge, but are sure to get some people annoyed.
As someone who uses Python but hasn't learned Ruby, this article got me to the same conclusion I alway get - while Ruby has a few very interesting differences and clever tricks I'd love to learn, it's so similar to Python that I'm better off learning a completely different language.
One thing I think is tiny, but incredibly helpful in Ruby, and I don't understand why more languages don't have it - the ability to add "?" and "!" to operators. That's an actually useful convention.
