I don't think you're asking the question that needs to be asked. Any case can have good or poor air flow. I've seen Phantom cases (huge, think full size ATX with room for eATX boards) that were overheating due to fan orientation problems, while uATX cases having similar components were acceptably warm.
Both of the cited cases are similar. For more internal space (I'm running off the assumption that cleaner wiring will likely offer you better air flow) and more fan positions, I'm going to give this to the Coolermaster.
Seriously though, cheaper cases don't have poor flow. Less thought out builds do.
You haven't seen anything until you've seen this.
Wow! I didn't know the blue screen of death could get a blue screen of death.
