Go for the B206. High inertia blades which don't peel is a good enough reason. There are many others.
If you are considering R44 or B206, I presume you can afford either.
From a flyer's point of view, the T-cyclic is my pet hate. It induces vertical as well as lateral movements and does not hover smoothly like a floor cyclic. I actually learnt on the R22/R44 but subsequently found out how stable floor cyclics are (eg H269, B206, EC120, AS350).
Get a B206 with high skids. Your stinger sits higher off the ground and there's more clearance landing on tall grass or bushland. They're also a lot stronger than Robbie skids - the latter crumple easily on impact (I've seen the results, not a pretty sight).
If you're getting a (used) B2, get a friend who's an experienced B206 engineer to calculate the replacement and future running costs so you can budget for it (no nasty surprises there).
I would go a bit further than 350boy - I believe R44s should be in the experimental category.
