I think that's also what I'm concluding, at least for myself.

My lack of visualization meant that I learned different ways to process information. I think some of these have let me work with abstract reasoning in a much more flexible way. I also very quickly recognize abstract patterns amongst wildly different domains (witness the less-than-a-moment's thought that eventually became the schwartzian transform).
Also, since I don't "picture" a conversation I'm having, I'm terribly efficient with word puns. I "hear" all similar words, and all different meanings, for each word in a conversation. I suspect that people who visualize an actual dog when I say "dog" would have a harder time doing that.
Like a blind person getting better hearing in exchange, my mental "blindness" has created a number of very useful skills.
