Sorry to hear you got a bum toilet, luckily for you, there’s the other huge benefit of low flush toilets that I didn’t mention.

Even with a total clog, there’s a 1-2 flush bowl capacity before it over flows.

Who remembers the abject terror of watching the water rise in a clogged high flush toilet and just praying it didn’t overflow.

Also unless every usage is a big poop requiring extra flushes, it’s far fetched that more flushes occasionally are adding up to the same water usage. If the toilet clogs for #1, something is very wrong - likely installed wrong, plumbing issues, or user error. Your toilet might not have been seated right so the wax seal ring is partially blocking the sewer line.
