Speaking as someone who has thought a lot about what helicopter to buy... though sadly not quite there yet financially, and not sure I'd really buy one anyway (the economics of owning a private heli for recreational flying are truly awful).
All but one of my ~150 heli hours are in R44s, the other hour in a G2. I really enjoyed flying the G2 and I'm not super happy with the teetering rotor in the R44. But on balance if I did buy one, I think it would be the R44, for the extra seats and because with the hydraulics it is easier to fly.
Now if there really was a G4, that would be a different story - especially if it had hydraulics. I don't think the extra initial cost would be a big factor, especially since for low-time flying the time-based overhaul limit on the R44 would kick in long before the hours limit did - making the R44 a lot more expensive than it initially appears.
