All of the tests that I've seen show that the aerator pumps are significantly slower than reversibles. The problem is that their flow rate is greatly reduced by any amount of head loss (pumping up against gravity in this case) - you will never reach anything close to their stated numbers like "1200 gph" in any real world application. The impeller pumps do not suffer as badly and will operate much closer to their stated numbers.
