Me and my crew will take climbing anyday. A good climber and rigger can move enough wood to keep the cleanup crew busy easily. A climber can also be anywhere in the tree anytime. No ruts, access problems, payments, huge guts, boredom, all the stuff that goes with the bucket. Now if you don't have that good driving force of a climber (or 2 or 3) than I could see the need for the bucket.
Climbers need to be in shape, with physical fitness comes your drive, we thrive on the physical challenge, even my dad at 55. Bucket work is not even as close to as physically challenging as climbing is. I realize that some of you see that as an advantage, but we can put all the wood down that can be handled without it, cheaper and in 95% of the situations. So for us no real advantage.
I do see 1 advantage for a bucket and that is working around power. We do some, but mostly residential work.
I am not trying to put anyone down that uses a bucket a lot, but for us it's just and unneeded expense. Keep taking the challenging path, stay fit, stay driven, and live long. That is of course as long as you don't become disabled or injured, then get a bucket or get out of tree work altogether, which for most with trees in their blood ain't gonna happen.
When times are tight and fuel is high, it's nice not to have that asset sitting there and the expenses looming.
