B206s are going to be more popular, particularly for commercial uses, with 4 doors and a bigger rear compartment (EN480 is really a 2+2). Other advantages - 2 blades easier to hangar and only needs two TT staps (EN480 needs 3). If it's going to be rented out, a 206 could bring in more income.
But, the 206 production is ending and the EN480 is still a current model. And, you'd get a much newer/lower hour EN480 (ideally 'B') for the price of an equivalent 206.
IMO it's a better first light/private turbine with safe, easy and forgiving handling and robust engineering. It was original designed to be a turbine trainer for the US militarty, and now seems to be selling around the world in a variety of roles.
