Verdict
The clearest difference is price: R at Free against Quiz buzzer full version's $4.99. R also leads on update cadence (every 8 days vs every 8 months). Quiz buzzer full version's advantage is iOS requirement (12.0 vs 15.1). On ads, in-app purchases and device support there is nothing between them.
