Verdict
The clearest difference is rating: Birdbrain at 5.0 against IQ Test's 4.5. Birdbrain also leads on ads (none vs shown) and review sentiment (100% vs 91%). IQ Test's advantage is ratings volume (55 vs 1) and iOS requirement (12.0 vs 15.1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. IQ Test sells 7 one-off in-app purchases and Birdbrain sells 4 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
Birdbrain holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: IQ Test has 55 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 91% of IQ Test's written reviews are positive against 100% of Birdbrain's.
