I'm not familiar with the nuance of either plan, but I think we absolutely need to focus on preventative treatment/lifestyle/medicine etc.
Also, I think the demand for healthcare services is just way too high for a variety of reasons. Among them is a culture of healthcare use/overuse/unnecessary treatments, which is partly due to having such an insurance-reliant system in the first place.
Health care should be ensured, not insured. Insuring health care is necessarily a loss for consumers and prohibitive for those who can't afford it. It creates barriers to access and raises costs disproportionately. Ensuring health care is difficult to achieve, but if done correctly, achieves goals of both availability and affordability of the health care system.
It's a radical move and cannot be achieved in one simple step, but insuring health care should be illegal and an alternative which guarantees service in a sustainable, quality way should be put in place. Until we do this, we are all losing. The question is just by how much.
