Depends. It took a while for me to get used to the Powershuttle. Even when I got fairly proficient at it, I still had to use the clutch at times because unless you are filling your bucket from a mountain of sand, not every bucket is consistent with the last one. Also, there is the issue of finding the correct gear in the first place. That can eat up a little bit of time while loading, too. Before I sold the 1540, I got to the point where I could usually avoid clutching, but even then, not entirely.
Even the big construction pay loaders are hydro, not sure why this is debatable.
Again, having said all that, I still think I prefer the Powershuttle over this Hydro (overall). It's just that I use our 1643 for loader work almost all the time and there's no question the Hydro is faster and easier to use in that role.
