For tourist work the comparison would really be KH4 v R44. The KH4 is a great tourist machine. Slow and stable, great with the doors off although the middle seat is a bit of a disadvantage.
The R44 has more power, better tail rotor authority, all seats are window seats but is not as comfortable in turbulence, and with front doors off the rear pax mics need to be disconnected so as not to interfere with pilot commentary.
I don't know that there are many 47s or KH4s left out there though. Heliwork has upgraded all theirs for 44s although with the ad on the 44s that has grounded most of their fleet during peak season they may be regretting that. NAH may still have one in the gorge ?? don't know for sure, last time I was thru they still had one at Vic River roadhouse.
It's a shame the 47s are disapearing. With less power, less tail rotor authority and no governor I think that they taught pilots better basic handling skills than the much more forgiving 44.
