The benefit of a larger maximum cassette size will allow for a greater gear range while also offering closer gear steps across the cassette for maintaining a comfortable cadence. With a 46/33T crankset paired with a 10-36T cassette, you achieve 502% gear range with a sub 1:1 gear ratio (.92). With a 48/35T crankset, you have a 494% gear range yet still reach sub 1:1 gear ratio (.97).
