Futurama holds a special place because it was on so many times while I was out at a party, or waking up in the middle of the night to adult swim on Cartoon Network, or hundreds of other occasions.
I enjoy it's geeky/silly brand of simpsons like slapstick and pun laughs.
Rick and Morty is a different form of enjoyment and I dig it for it's crudeness, and it's harshness mixed in with lots of surprisingly well pulled off fantastical elements.
Different enjoyments, both are great to me.
