Yes. I've not run the Giant loaders, and I couldn't tell what model that was, so as to compare the exact specs. I have the Bobcat A300 and it is truly awesome for tree work.
I would guess that within the same weight class, the Giant has a greater loading capacity and has considerably more reach. The A300 will get into smaller spaces and will run circles around an articulating machine. Both will be fairly easy on turf and pavement, but the A300 can be equipped with floatation tires for almost no tracks on firm ground. That being said, when an almost 10k machine carries a 3k log out of the back yard, it's going to put depressions in loamy soil, whether or not it tears up the turf.
The A300 will be considerably more versatile, as it can switch to skid-steer mode, and work very tight quarters with any skid steer attachment. The operator's 360° visibility will be much better on the Giant, but the A300 will outperform the articulating loader on steep slopes, as it has a lower center of gravity (providing you don't try raising that loader too much!). Should you goof up and roll them both down a hill, the Bobcat will incur less damage, but it will have a greater tendency to keep rolling once it is started. The Giant will have vastly greater stability against rolling over backwards (a real weakness of all skid steers), so it should outperform the A300 driving empty up a hill to recover a load.
If I were to dial in my ideal equipment for loaders, I'd want the articulated loader for it's greater capacity, and I would dream of having a smaller machine than the A300 that still had the switchable-wheel steering in a lighter package. I think all the tiny skid steer machines like the Dingo are not so good an investment, once you learn how much traction is thrown away skid-steering around on every job. Too bad nobody makes a smaller version of the A300.
Until you try the A300, you just cannot appreciate how much traction is just thrown away on skid steering. I've been hopelessly stuck countless times while in skid steer mode, but I just flip the switch and go to 4-wheel steering and usually drive right out. There is a lot to be said for having 4 wheels all pulling in the direction you want to go, but that is a trait shared with all the articulating loaders, too. Digging power while grading or loading materials is similarly improved.
