Verdict
The clearest difference is rating: RUN interval at 4.7 against Sprint's 3.7. RUN interval also leads on ratings volume (1K vs 3). Sprint's advantage is in-app purchases (none vs 2) and iOS requirement (13.0 vs 15.6). On price, update cadence, ads and device support there is nothing between them.
