Don't know much about the 407 other than what the guys who have flown it told me, A LOT of power!
The 427 is very realiable. The only issues my company has had, have been avionic related, IIDS display sometimes playing up, and the occassional small things when the aircraft first came out, from what I have been told.
If you PM me, I can put you in touch with the Engineering guys here, and they might be able to answer those questions better.
And to answer your other question: They are VFR/NVFR. Bell were originally going to certify it latter as SPIFR I believe. They are now concentrating on the 429 I guess, which according to the specs should be quite good.
Cheers BigMike
*The 427 is also certified Cat A.
