Verdict
The clearest difference is in-app purchases: Studio TwentyFive at none against AS Log's 3. Studio TwentyFive also leads on iOS requirement (15.6.1 vs 17.0). AS Log's advantage is update cadence (every 10 days vs every 3 weeks). On price, ads and device support there is nothing between them.
