the EC120 is what the 206 should have evolved into.
The lack of the bulkhead makes it more pleasuable for both pilot & pax. Obviously the 120 will have teething problems and eurocopter are making improvements all the time, whereas the 206 is a great reliable workhorse. With little competion to challenge the 206 for the past forty years, Bell didn't really need to spend more money developing the machine( and getting approvals $$$)
