One difference you really notice is the age of the design of the two machines. B206 - sixties technology and ergonomics. EC120, mid nineties. Everything from built-in safety/crashworthiness to passenger comfort and view has evolved in that time.
Payload/range of the EC120 can be a problem if you need to carry four big pax and their luggage. You won't get very far. But for private flying and joyrides, I don't think you can beat it. Unless you can afford an EC130, in which case go for it and enjoy, and can I have a go???
