Regardless of whether or not you're operating an aerial lift or climbing, I think properly trained people are safer.
Sure there are those special cases when one approach is obviously more preferable than the other, but on average, I don't think the comparison is fair.
Climbers, especially productive climbers, have learned or been trained for years on what or what not to do in a tree. On the other hand you can "train" someone to use a bucket in a relatively short amount of time. If the statistics included whether or not the operator actually knew the basics of tree work aloft I think the conversation would change. I believe the results would reveal that the method of ascent into the tree is not nearly as big of a factor as experience in cutting and rigging aloft when it comes to measuring safety.
