Good post HV. Personally, I have about 2,500 on the 350, and only 1,500 on the 407.
As you mention, the type works for us, we move a lot of people short distances, and the 407 can do it fast. Sitting rearward is not an issue, one-time riders for 5-10 minutes don't complain, The gear room is not an issue (although we have a huge ski basket), the fuel range is not an issue in this country (everything is close, it's all vertical distances, and a 407 can climb like a home-sick Angel).
We are a Bell-only company, and have tremendous factory support. VR is a breeze, with a huge VR bubble window, plus I'm only a svelte 5'-8"
MAG knows my biggest beef with 350's, RA, GH, SH,
