Depends on the operator (s) the older models are pretty reliable, the newer ones are easier, hard to say on production numbers. You would need to have it in a situation where depth was an issue and you have plenty of trucks too see which could go faster. The newer console is easier to operate, I went a little faster with it than the older setup....but it would boil down too who is operating and how much experience they have with whichever model they are used to running. The drives are pretty much the same.
