I know mass moreso helps specifically with how hard an object is to move around, but what about a massive object that is less dense than another but still has more mass overall, would it be harder to deform all else equal?

>all else being equal
If you used the same substance but made it denser, then it would be under extremely high pressures. It’s pretty much impossible to hold “all else equal”.
The way an object responds to slow deformation has nothing to do with its density, at least not directly, and the way it responds to *fast* deformation is almost exclusively related to density. This is because inertia – something that mass gives to an object – responds to rate of change. A fast impact is a sudden change, a slow impact is a very drawn out change.
