What is relevant is the sectional density, so how many kg you have per square meter, in SI units. https://en.wikipedia.org/wiki/Sectional_density https://en.wikipedia.org/wiki/Sectional_density A single larger sat would usually have a higher sectional density. But as far as I am aware, nobody else is launching into such low initial orbits, no matter the size of the sat. Usually you want to launch into an at least somewhat stable orbit so you have some time for troubleshooting in case something goes wrong.
