Softest, cuddliest yarn?

I am going to attempt this comfy looking Curtain Call Sweater from Lion Brand, but want to use some luxuriously soft and comfy yarn. Is Malabrigo my best bet, or is there something even better? Thanks.

wow that’s be cozy made of malabrigo!
I am using some right now, to make a wrap. It is VERY soft.
I couldn’t believe when I saw that Lion “Glitterspun” is worsted weight?!
I have used it before and it seemed a wee bit finer than worsted. I guess maybe because it has no fuzzy halo, it appeared finer to me.
