Verdict

The call

The clearest difference is rating: Electrical Engineering at 4.7 against Engineering HandBook's 4.0. Electrical Engineering also leads on ratings volume (252 vs 4). Engineering HandBook's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price and device support there is nothing between them.
