Actually, I wonder how it compares when you consider 12 hours of fighting the air resistance versus a sub orbital hop covering the same distance in 30 minutes with only a couple minutes of draggy atmospheric flight time. Also the methane used by Starship could be synthetised possibly used captured CO2 if you had enough power available for that.
