Could it be that 2 engines are better than 1
212 versus 214b's
Comparing the performance of a 212 to a 214B is like comparing the 214 to the Crane, they are wholly different aircraft and performers.
A loaded, straight, 212 on one engine has all the performance of the 214 on none!
Two engines certainly may be better than one for many applications and environments, but they don't translate into a guarantee of performance, or safety.
