The clearest difference is ads: DNSecure at none against AdSpamBlock's shown. DNSecure also leads on monetization model (free vs free with in-app purchases) and review sentiment (88% vs 79%). AdSpamBlock's advantage is update cadence (monthly vs every 3 months) and ratings volume (640 vs 109). On price, rating, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
