I don't know that every Savannah is the same just like your Aby is probably quite individual also. From everything I have heard from Aby breeders while hanging out at cat shows over the years, they are very similar in personality. It is the breed I most liken Savannahs to in terms of behavior.
Additionally, many adult cats are just not keen on strangers...hence you may not find when visiting that the cats behave as they would with their owners. This is something that comes up in Rescue, many folk want to go meet the cat before adopting. With a shelter environment, that is possible and usually the animal would then be motivated to reach out to a stranger as they just want out of that place. But in general, when people go to meet a cat in the cat's home, the cat is only comfortable with the owner and is not motivated to interact nor bond with the new person...so we find the adopter will often back out thinking there is no initial bond they are expecting. You might find that the Savannah in that home you are visiting is not too interested in interacting with you initially... depending on how many strangers it has been exposed to in its life. So you might be disappointed and think as a breed they are not as interactive nor social as you are expecting, because of that one cat. Or on the flipside, meet an amazingly social one and have high expectations of your own kitten.
I understand that an F2 is a large investment of money, but I wonder if your research would be better driven by asking questions about specific concerns you might have? Is it the size, the ebullience...the troublemaking tendencies?
