Electric motors clearly can be better than ICE. They have fewer moving parts, need fewer subsystems, are much more efficient and clearly are quieter. They are lighter, more compact and the list goes on.
If they cause CO2 to be produced I care not at all and do not list this as an electric advantage, but even so they are better in many categories.
The problem is batteries suck for aviation purposes, and due to the limitations of the periodic table always will and are a dead end. The reason this is being pushed is political and ideological, it has nothing to doo with aviation.
HFC technology has potential for providing power, but Li batteries, no.
