TOTO Drake Two-Piece Toilet vs American Standard Champion 4 Toilet: Which Should You Buy?

Both toilets have a MaP score of 1000g, meaning they can handle up to 1000 grams of waste per flush. The MaP (Maximum Performance) test measures how much solid waste a toilet can clear in a single flush, with 1000g being the highest rating for residential models. So in terms of raw capacity, they are equal. However, the flush systems differ. The TOTO Drake uses a G-Max siphon jet, which relies on a large water surface and a siphon to pull waste out quietly. The American Standard Champion 4 uses a piston action accelerator that creates a more aggressive, rapid flush. For heavy waste, the Champion 4's 2-3/8-inch trapway gives it a slight edge in preventing clogs, but the Drake's siphon jet is quieter and still highly effective. For most users, the flush power is comparable, but the Champion 4 is better for extreme waste loads.

The TOTO Drake is the clear winner in water savings. It uses 1.28 gallons per flush (GPF) and is WaterSense certified, meaning it meets EPA standards for water efficiency. The American Standard Champion 4 uses 1.6 GPF and is not WaterSense certified. Over a year, the Drake can save about 2,200 gallons of water per household compared to a 1.6 GPF toilet. The Drake's lower water usage does not compromise its flush performance, as it still achieves a 1000g MaP score. If reducing your water bill and environmental impact is a priority, the Drake is the better choice. The Champion 4 uses more water but offers a larger trapway for clog resistance, which some users may prefer despite the higher water consumption.

The American Standard Champion 4 is better for heavy waste and clog prevention. Its 2-3/8-inch fully glazed trapway is significantly larger than the TOTO Drake's 3-inch trapway. This wider passage allows larger waste and more toilet paper to pass through without blocking. The piston action accelerator flush also provides a more forceful, direct flush that clears the bowl quickly. While the Drake also has a 1000g MaP score and performs well, the Champion 4's trapway size gives it an advantage in situations where clogs are a frequent concern. For homes with multiple users, heavy usage, or a tendency to flush large amounts of paper, the Champion 4 is the better option. The Drake is still excellent for most households, but the Champion 4 is the specialist for no-clog performance.
