I’ve flown both and know the difference, they were the first two types I flew when I got my CPL, give me a C206 over a C210 for bush work any day. As these are aircraft that are likely to be flown in commercial operations by those at the lower end of the experience spectrum, this may be reflected in the accident rate. Also they are very common types so they are likely to feature more often in accidents and incidents.
Both are decent aircraft and should present no problem if correctly maintained and operated. However, being typical first job aircraft they are the ones new CPL holders are learning from their mistakes on.
