We just gutted all of our bathrooms and I have two "boys" (i.e. son and husband) in the house. I specifically told the contractor I needed something that will flush! We went with all Toto, but I did NOT go with comfort height. Personal preference, but if you're not tall or have kids, comfort height toilets will be too uncomfortable - you'll be on your tippy toes sitting. Now my husband is 6'2", so we could have gone comfort height for him, but he said he didn't care and I did. I've used comfort height toilets in hotels, and hate them. Now, once I"m old and retired, I might change them out for comfort height as its easier to sit down on them, but that's quite a few years away.
