Ooh, comfort wise, I don't think there's much in it generally, but my 156 is better over longer distances than the spider. I'm making the rash assumption your Brera is similar to the Spider? It's subjective I know.
Having never driven a Spider, I also assume they're likely to be broadly similar. My Brera is equipped with the 17" Wheels That Must Not Be Named
, which contribute greatly to a comfortable ride (compared to the couple I drove with 18" horsehoes).
I think in comparison with my outgoing car, which was a 2.0 147, the (mostly standard) 147 GTA seemed
'hardcore'; while the Brera, being completely different, seemed like a solid GT. I don't know if that's absolutely accurate, but it's the impression it left with me. Having said that, I've been increasingly into Alfas, and the GTA is feeling like an itch I will need to scratch sooner or later
Suppose we'd better keep this slightly on topic: Averaged 10.8 mpg over the couple of hundred yards to the indie garage this morning
