I think calling solar a little more performant is underselling it. Once you have LEO getting to a better orbit costs relatively little. Getting from LEO to the moon is only like 30% more than getting from ground to LEO.
True, but lifting the fuel to power that “small” orbital boost is unintuitively expensive
