What is the best Hydraulic Excavator (backhoe) in the world?
That is an impossible question to answer. It would depend too much on where you were, what you were doing and how heavily you weighted each of the criteria. But then that’s true for just about any “what’s the best…” type of question. There may be a best choice for one person in one particular situation but it is very rare that there is a clear best choice for all situations.
