Again, why are you comparing slight differences in GPA? The reason why I discourage using engineering as “good preparation” for law school is that you’re going to take about a half-point hit on your GPA, minimum. Those engineering classes are scaled to a 2.5.
The question isn’t about what a law school would do with hypothetical applicants; it’s about whether you would be better off applying with a 3.6 in history or a 2.8 in EE. And that question answers itself.
