Here you go, Rich! The brands I have access to/sell are Gehl, Avant, and of course Giant (this thread). Avant doesn't offer much now with Giant in the mix. Giant has machines bigger and smaller than the Gehl lineup, but the Gehl machines are roughly cheaper.
1: Articulating Loaders are Super Easy on Grass Compared to Full Size or Mini Skid Steers, tracked or wheeled.

2: Mini Articulating Loaders Drive Faster and Lift Higher than any Mini skid (Giants drive faster and lift higher than Avants).

Note using the telescoping boom to get out of/over the soft areas with the turf tires as well as increasing reach to grab material. 11 minutes starts the ~200 yard drag to the chipper.

3: The Mini Articulating Loaders (BME Giants and the 2 smaller Avants) are Small Enough to Fit Sideways on a Truck/Trailer.
4: Articulating Loaders and the Branch Manager Grapple Make a Perfect Combo for Feeding Chippers.

Not the best terrain (super soft ground) and the Avant is harder to steer backing up as you sit on the front section.

Specs. The width isn't correct (new tire option to get through a 36" gate) and they will have a mini skid universal plate, but this shows the gist.
