It's definitely a con for human habitation. Our physiology evolved in 1g and without that many of our bodily processes behave poorly over extended timeframes.
We don’t actually know what the long-term health consequences of Martian or lunar gravity are.
We know the long-term health consequences of microgravity (as in LEO) are significantly negative.
But, we lack data on long-term health effects of Martian or lunar gravity. Pessimistically, humans really need close to 1g, and anything significantly less causes serious problems-lunar isn’t going to be much better than microgravity. Optimistically, humans just need “some gravity”, and while close to zero is harmful, lunar or Martian isn’t.
The way things are going, we are likely to find out in the next 10-20 years, at least for the lunar case. If lunar gravity avoids most of the negative health effects of microgravity, Martian gravity will too. If it doesn’t there is still the chance that Martian gravity might be “just enough” even if lunar gravity isn’t
