CO2 per kWh focuses purely on the issue of attained performance of electricity production - which is the main matter for production technology to concentrate on. Dividing by GDP flatters the view of wealthier nations, and GDP itself is not a real measure of wealth or benefit to self and others. The purely technical measure of CO2 per kWh avoids argument of who is most/least beneficial by examining where production is performing best.
