Detailed Comparison
Internal American Standard match: Champion 4 ($380-450) vs Cadet 3 FloWise ($175-195). Both 1.28 GPF, both 1,000g MaP, both two-piece elongated. The Champion 4 has the larger trapway (2-3/8" vs 2-1/8") and oversized 4" flapper — engineered for higher clog resistance. The Cadet 3 has a slightly smaller trapway but is still rated at 1,000g MaP. For a high-use household, Champion 4 provides additional headroom. For typical residential, both perform reliably.
Final Verdict
We recommend the American Standard Champion 4 for primary bathrooms and households prone to clogs — the larger 2-3/8" trapway clears loads the Cadet 3 doesn't. The Cadet 3 FloWise wins on price and remains the sweet-spot value pick for guest bathrooms and apartments.
