Verdict
The clearest difference is monetization model: Forthcoming at free with in-app purchases against iDocSet's subscription. iDocSet's advantage is update cadence (every 2 months vs every 6 months) and iOS requirement (11.2 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.
