The clearest difference is review sentiment: GraviTrax at 74% against Epic Marble Run's 27%. GraviTrax also leads on rating (4.4 vs 2.9) and ratings volume (154 vs 12). Epic Marble Run's advantage is in-app purchases (none vs 1) and update cadence (fortnightly vs every 5 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. GraviTrax sells 1 one-off in-app purchase. Epic Marble Run asks for nothing beyond the download.
