Done it a lot at uni, but not after, sadly.
I noticed some pairings went great for me and some... not so much.
I tend to be a creative but chaotic, the right partner made the difference between "hey don't you mean < rather than >?" and "You broke it! Why can't we do it the simple [lower-quality] way?". In the first instance our AI beat all our classmates', in the second our 'robot' shot as far to the left as possible regardless of inputs.
Based on those experiences and discussion with others, I started to believe pairing men and women together works best.
