Verdict
The clearest difference is update cadence: ModMap at daily against BuildSheet's every 9 days. ModMap also leads on review sentiment (100% vs 75%). BuildSheet's advantage is ratings volume (46 vs 5) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.
