It’s not a this or that thing but a mix of what is smart/reasonable/popular determining what to spend space dollars on. My money is on space based (orbit and moon) observatories as well as learning to live in appropriately sized communities firstly on Luna or at colonies (RAMA comes to mind) in local orbit. Robotic probes to our neighbour planets is vital if we’re to understand our solar system and needs boosting even though it’s not as sexy as a manned presence. Time to take a rational look at costs and knowledge gains.
