Although I love both, I feel the R44 has the edge for what you want to do, in spite of having one less seat.
From the viewpoint (literally) of pax, it's as good as an old saloon car without headrests! - Those in the back have a brilliant view. In the 206 they are, and can feel (in my experience) cut off from what is happening.
I assume the reduced running & mainytenance costs will make up for the missing seat, in Australia as it does elsewhere?
Also, the hydraulics now make the R44 feel like a JetRanger to fly, as I don't doubt you have experienced for yourself AND you can choose to land on water, if you're allowed to, which is "divine"!
It's easy to obtain a very smart and presentable R44, whereas a reasonably priced 206 could possibly be scruffy and smelly, which is a real turn-off.
Well - there's my tuppenceworth!
