Not just likely easier. Far easier. They're so far apart on any reasonable effort scale that the comparison is basically meaningless.
Or even before that, fixing the habitat of the planet we are living on. A lot of the current cultural fantasy of colonizing space feels less like expanding the human frontier and more like escapism.
