The Barons have a very high nose att when landing, lots of drivers had truble keeping the nw high enuf.
Yep, the Baron is the RR of light twins.
The 310 has a lot more room in the cockpit, at least you can take a deep breath with two largish people in the front.
As everyone says, bout the same for range, fbo, TAS, etc,etc. I've 1000 plus in each, so my choices are:
the Baron for stability n handling, the 310 for room, esp the wing lockers.
