to be fair socialized medicine is quite good in the majority of europe, obvious exceptions though (like the uk is comically bad because they almost entirely defunded it while mandating it for many treatments), and also gets less subsidies from the government on average than the u.s. does last i checked.
given americas situation and the stranglehold of the medical industry legally it makes much more sense focusing on bettering insurance rather than a total overhaul that will never make it through the courts. (and cheap decent private care is always an important alternative to have to avoid being trapped in a bad social system). focusing on a very half assed social system as kamala did is dumb, trump actually did better some things in healthcare ie insulin. if either of them wanted easy wins they could avoid the changing the programs and just bump up the (generally quite low) thresholds for medicaid, which shouldn't make a huge difference in cost, but that's a very cheap shot
trump is definitely better there in terms of actually standing up to the lobbyists that made it so awful to some degree
