Verdict
The clearest difference is update cadence: Marla Blue at every 4 days against Surf's every 6 weeks. Marla Blue also leads on review sentiment (100% vs 87%). Surf's advantage is ratings volume (940 vs 4) and chart position (#116 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Surf sells 2 in-app purchases, starting at $4.99 per month and Marla Blue sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.9 for Surf against 4.8 for Marla Blue. That said, the two scores are not equally well evidenced: Surf has 940 ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 87% of Surf's written reviews are positive against 100% of Marla Blue's.
Surf ships an update every 6 weeks, Marla Blue every 4 days. The most recent releases landed on October 16, 2026 and October 18, 2026 respectively.
