Verdict
The clearest difference is in-app purchases: Powerfish at none against Electrical Engineering's 8. Powerfish also leads on ads (none vs shown). Electrical Engineering's advantage is update cadence (every 2 months vs every 6 months). On price, device support and iOS requirement there is nothing between them.
