I found a thread from 4chan under /c/, here's what 2 anonymous users had to say about chubby girls in a chubby anime girl thread.
I've heard chubby girls make some of the best waifus, because:
1. They often know how to cook
2. They tend to be sweet
3. They are better for snuggling, and
4. More cushion for the pushin'
Lesser-known perks:
1. Fat keeps the skin elastic, resulting in fewer wrinkles
2. Many of them won't expect the attention, so they tend to be more enthusiastic about sex
3. Chubby cheeks are the cutest, have you even seen them
