Verdict
The clearest difference is rating: Gray Line at 4.9 against POPGuide's 4.3. POPGuide's advantage is ratings volume (3.6K vs 7) and chart position (#179 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Gray Line holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: POPGuide has 3.6K ratings behind it against 7, so its average is the more settled of the two.
