Verdict

The call

The clearest difference is in-app purchases: Digital Electronics Guide at none against Electrical Components Quiz's 4. Digital Electronics Guide also leads on update cadence (every 5 weeks vs every 12 months). Electrical Components Quiz's advantage is ads (none vs shown) and ratings volume (7 vs 2). On price, rating, device support and iOS requirement there is nothing between them.
