I need informed opinions on Senegal or Crimson Bellied Conure as a pet bird!?

I have narrowed my decision to either a Senegal parrot or a rather new to the pet world - Crimson Bellied Conure. I would like opinions as who would be sweeter, more cuddly, less nippy, quieter and overall love to hang out with me. I have 2 breeders of each on standby and both tell me to get there's... :) Both breeders hand raise and flight suit train there birds and both say theres are the best. I am not new to birds, I have had atiels and doves and currently have 2 budgies. I want the "next level" bird. I also know each bird is an individual, I'm looking for generalizations and people who have experience with both. Please help... I'm struggeling with a decision and need to put a deposit on one or the other very soon.
