Not unsafe, but less safe than the modern equivalent due to improvements in the certification requirements, and other improvements such as HMI and autopilot functionality, especially when you bear in mind that "pilot error" is still a popular way to crash. Take the case of the recent AS332L2 crash at Sumburgh, that accident could have happened to an AS332L or an AS332L2. Had the same pilots done the same thing in an EC225 that crash wouldn't have happened because the heli would have stopped itself falling into the sea. So in this respect (and many others) the modern EC225 is much safer than the older AS332L and L2, even though the latter are still performing as the manufacturer intended.
