Defining or plumping lips with Restylane and/or Juvederm

so confused between restylane & juvederm. everyone says they are both good.. but i need to pick one i'm looking to have very full plumpy lips. not sausage looking but just plain plump & pouty, so that even without lip gloss they look huge in a good way. i like my lower lip, want to increase my upper in terms of volume.. and even increase the lower a bit..
