My primary business is finish grading. I use a skiploader and a skidsteer. I have tried 3 different skiploaders (Case, Newholland, & Deere). I can't help you on the Cat. I prefer the Deere and am on my second one. Sold the first one at 4K hours and have 5K on the second one. Both have had 4in1 buckets which I find extremely useful.
I found the Case hydraulic controls to be too jumpy/jerky for fine finish grading, and the Newholland just seemed rough compared to the Deere.
On my first Deere, I replaced the front tires, the battery, and one hose. On my second Deere, I have replaced the front tires, the battery, 2 hoses, and a hub seal. They are reliable, hard working machines with smooth controls.
