For me it's the 3200 overall. I think it looks better with the rear lights and bonnet vents, it's rarer, the last of the genuine Maserati engines, the interior is better quality (no fake leather like in the 4200), and although the performance is similar, when I get in the 3200 after using the 4200 for a while it feels much quicker - no doubt just the nature of the power delivery, but definitely more of a kick. Conversely, I love the look of the engine in the 4200, I prefer the more instant throttle response when you blip the throttle, and to me the 4200 sounds better. I've put Larinis on mine and left the 3200 standard, but even in standard form I think the 4200 sounds great. Both have been equally reliable and dependable. However, I may be tempted by a Gransport, and this may be my next car - to my mind its looks compensate for the 4200 omissions, it has a more sporty setup and I like the interior.
