Verdict

The call

The clearest difference is ads: Star at none against Electrical Engineering's shown. Star also leads on iOS requirement (12.0 vs 17.6). Electrical Engineering's advantage is update cadence (every 4 months vs every 27 months). On price, in-app purchases and device support there is nothing between them.
