As a former 'tour' pilot on the H130 I would second all the positive comments so far (especially with the upgraded aircon that the T2 now has). Customers like it because not only do they get a great view in comfortable seats, but they can chat to each other and discuss what a great time they are having without high-frequency sound-waves setting their teeth on edge.
One other thing that the H130 offers is the very reduced external sound-footprint if it is flown to the right profile. So it is not just the people onboard who benefit; the aircraft can be spookily quiet if flown conservatively on disciplined flight-paths. This can make all the difference to those neighbours who might object to the thought of regular helicopter traffic.
Mind you, none of this is cheap and pilots agree that the B407 is a fine aircraft; but then they aren't paying the bills.
