Verdict

The call

The clearest difference is ads: Power Electronics at none against Electronic Devices Quiz's shown. Electronic Devices Quiz's advantage is update cadence (every 3 weeks vs every 2 months) and iOS requirement (12.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
