Verdict

The call

The clearest difference is price: REGA Decoder at Free against CPU X's $2.99. REGA Decoder also leads on iOS requirement (14.0 vs 16.0). CPU X's advantage is update cadence (every 10 days vs every 12 months) and device support (4 vs 2). On ads and in-app purchases there is nothing between them.
