Depends on your requirements, but as a business acft AS355N has strong package of reasonable speed - 130kts, good range - realistic 350nm, and very good payload - full fuel + 4/5 POB, so IFR range pretty good with 4 pax.
Add reasonable running costs, great reliability, a very comfortable, fairly quiet ride for 4 pax, ability to take 6 if needed, and it is hard to beat as the inevitable compromise if you're paying your own bills!
