Ronbus Quanta Pro R3 vs Ronbus Quanta Pro R4
The Ronbus Quanta Pro R3 is a 16 mm elongated paddle; the Ronbus Quanta Pro R4 is a 16 mm hybrid one. Across the 6 specs with a clearly better direction the Quanta Pro R4 takes 3 and the Quanta Pro R3 takes 2. The Quanta Pro R4 swings lighter (113.0 vs 118.0) — quicker hands at the net, where the Quanta Pro R3 plows through the ball instead. That is a preference, not a win. They retail for the same $120.00.
