Gaunty,
Have flown both the Baron and 310 but it has been a while since I was in a Baron. I loved the Baron and was not a massive fan of the 310. My memory is most likely failing me, but I do seem to recall the Baron being better in turbulence. The 310 does yaw a lot when upset and quite often the yaw dampers don't work. However the 310 is much better for charter; more room, payload etc. I just felt it was more of a work horse where as the Baron is a lovely sports car. A helluva lot easier to land well than the 310.
