OTOH, I've had the good fortune of working in a team of top 10% engineers/architects (I'm not top 10%, btw) who worked harmoniously, and it was one of the best times I ever had in my career. Learned a lot, upped my level trying to keep up, helped create a good product, etc.

In that case, the key was that clumps of them had already worked together in earlier jobs, so the incompatibilities had been pruned.
