Verdict
The clearest difference is ads: HAP Studio at none against oIDFA's shown. HAP Studio also leads on update cadence (weekly vs monthly). oIDFA's advantage is monetization model (ad-supported vs free with in-app purchases) and iOS requirement (15.1 vs 26.0). On price, in-app purchases and device support there is nothing between them.
