PDSD is correct on length of methods. The methods given in an example in CC are ridiculously short. CC is more correct on comments than PDSD. Especially mandating comments in certain places leads to very low quality and, frankly, utterly disgusting comments point out, helpfully that the 'get_height' method 'gets the height'. CC is more correct on TDD than PDSD. The noticed danger of just focussing on implementation details over the structure of the API is always there but TDD has a refactor step to fix that. The general idea of working in small steps with there being a safe state between every small step is worth its weight in gold.
