Does anyone with experience with both Aquia I & Aquia II have any guidance on whether to buy one vs the other? I am leaning toward the II but hesitate because it looks like the I has MAP of 800 vs the II having MAP of 500. I have one bathroom in my flat which is used by my wife and our two toddlers, so both flushing reliability and cleanliness are very important. (I'm also willing to consdier Aquia III if performance justifies it, but would rather not have the ADA height because of the toddlers.)
