I'm not familiar with the others, but I also have a deltec MCE600 and it does a pretty good job. The best part about it is not having to worry about it overflowing. It is very consistent and never requires adjustments...pretty much set it and forget it. If it were to overflow or if you forget to clean it out before it fills up, it just overflows back into the tank. My only complaint is that I have an older model and it's pretty noisey from the vibrations of the pump. This problem was fixed in the newer models and supposedly they sell kits to fix the old ones but they are hard to find.
