Honda electric deployment is better, both because their efficiency saves that power through the lap, and because that electric engine is just better at recovery. Everyone has been saying this forever and it has been confirmed in this forum.
Ferrari's ICE on the other hand is the better ICE, less confirmed here by insiders but plenty of articles from last year quoting other teams (RBR and Merc) saying this.
Even with these 2 aspects, the difference is only a few bhp overall. Out of 1000bhp, if you manage 10bhp more you have 1% more power but sadly speed goes at the cube of power meaning you're at best looking at 1-2kph due to engine at equal aero efficiency. You would notice it more in acceleration but that's a lot harder to grasp and depends on more factors like traction, gearing and so on.
If you are looking at exolanations for why a car is 10kph faster than another this year, it's unlikely due to the engine.
