Detailed Comparison
Champion 4 ($380-450) and Drake ($340-380) compete head-to-head in the mid-tier two-piece category. Both 1.28 GPF, both MaP 1,000g, both 12" rough-in, both elongated. The differentiators are trapway size and flush approach. Champion 4 has the industry's largest residential trapway (2-3/8") and an oversized 4" flapper — engineered for maximum waste clearance, exceptional clog resistance. Drake has a standard 2-1/8" trapway and TOTO's G-Max 3" flush valve — refined, efficient, but tighter clearance. For high-fiber-diet households, septic systems, or anyone with chronic clog history, Champion 4 is the clearly better pick. For typical use, Drake provides equally reliable flushing with arguably better long-term bowl cleaning if the Tornado Flush variant is selected.
Final Verdict
We recommend the American Standard Champion 4 for households prone to clogs — the 2-3/8" trapway and oversized flush valve clear loads that the Drake struggles with. The Drake remains a refined choice for normal household use where Tornado Flush bowl-cleaning matters.
