Verdict
The clearest difference is price: Brain Storm at Free against The Guides Compendium's $0.99. Brain Storm also leads on update cadence (every 10 days vs every 25 months). The Guides Compendium's advantage is ads (none vs shown) and chart position (#85 vs unranked). On in-app purchases and device support there is nothing between them.
