Sudden evacuation might be problematic. But with less serious problems, the lower transit time to Mars vs. Europa might be advantageous. You're dead anyway within about 24 months from the lower gravity and radiation (or suicide, if sickness doesn't get you first).
There's no experience with humans living in low gravity conditions for more than a few days. We have plenty of zero-g experience, but none that would tell us what a few months of 1/3 g would do to the human body.
Radiation is a problem, though. Shielded habitats would be a high priority. Either underground, or possibly by using water (produced on-site) as shielding.
