Verdict
The clearest difference is price: PriceCharting at Free against OSSGA Material Reference Guide's $6.99. PriceCharting also leads on update cadence (every 8 days vs every 22 months) and chart position (#40 vs unranked). OSSGA Material Reference Guide's advantage is in-app purchases (none vs 3) and iOS requirement (8.0 vs 16.0). On ads and device support there is nothing between them.
