Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Objective-driven MOBA with shared team XP.
Command & Conquer: Generals leans Reads (Grand Arena); Heroes of the Storm leans Reads (Mind & Math).
Command & Conquer: Generals leans a little harder on execution, though the gap is small.
Command & Conquer: Generals
Supply drop timing and unit special abilities require precise activation
Heroes of the Storm
Skillshots and rotations require hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Command & Conquer: Generals
Three-faction asymmetry and general powers must be predicted constantly
Heroes of the Storm
Team-fight cooldown trading is prediction
Heroes of the Storm leans a little harder on variance, though the gap is small.
Command & Conquer: Generals
Supply depot placement is map-fixed; minimal in-game RNG
Heroes of the Storm
Map objectives and merc camps vary
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Command & Conquer: Generals
General power sequencing and unit composition are well-solvable
Heroes of the Storm
Talent picks and team comps deep
