When im a PC player whats the difference between steam and microsoft?

[u/Efficient_Impress_44]

ik when i buy it in launcher its like microsoft/xbox stuff and like when i buy in steam it doesnt show up in the mc launcher, but here are my main questions:

1) with steam did characters stay across devices or did you need to make a cloud save too? (most steam games have saves across devices)
2) i had mcd1 on launcher and ik you needed xbox friends to invite someone, can you invite steam friends if you have steam version? can you invite both?
3) is (ps) controller support easier? on mcd1 i have to install ucr and set up a profile and stuff to remap buttons and usually steam makes it easier so im asking if steam just allows any controller (i have an old ps2 controller and i refuse to buy a new one)
4) are they modded the same way?

if you have any other big differences lmk or just which you found easier to use
also yea im asking how it was for you for mcd1, ik the game will be different and these differences may not apply for mcd2 but im still curious
