I guess I would say that most here have bucket's, other than some of the small res type companies and mom 'n' pop;s. There are so so many tree jobs that a bucket is not a factor. Even with great access, would you prune a monterey pine with it? Most prunes are best when climbed. Even some removals are easier and faster if the bucket happens to be in the way of creating a larger DZ. It's all about application. I (we) here in Socal often see the (one of the) larger companie's (WCA) doing road work and freeways. They got all the stuff. So, on a major street here, has about 100 or so Canary Pines in the median with 2 lanes in each direction. They do not climb. They got 2 boom trucks for each tree. Probably an hour or so set up for traffic control, then the 2 guys and their boom's set up on either side of the pine and each one trim's a side. Maybe it works for them, but I would (with all that traffic control) have six trees at a time going with no boom. All depends.
