Whenever you install a new modpack, it copies the whole code for vanilla Minecraft, the assets, everything. As you can imagine, a number of modpacks takes up a lot of space. MultiMC somehow uses the same jar and resources for the same versions of MC for multiple instances, and saves as much space as it can. I also like how it gives you so much more control over everything, including what mods you use.
