For my property, a tractor makes more sense. It's hilly and open. I have fields to mow, ground to work, and fences to put up. While all of those things can be done with a skid loader, it's easier on a 51 HP tractor. My FEL has a skid steer quick attach, so I can make use of skid steer attachments and I have the third function hydraulics so I can do just about any of the powered attachments too.
The big kicker in tractor vs. skid steer is a PTO. Skid steers don't have them. A PTO driven brush hog or field mower will be more efficient than a hydraulic version. PTO implements are usually significantly cheaper than hydraulic versions (i.e. post hole digger). For implements that have to run a long time, PTO wins out because a hydraulically driven implement will eventually overheat the fluid without an added cooler.
I came home today to 10" of snow and my house is on the top of the hill. After driving up the driveway (AWD Volvo with real snow tires), I drove my tractor to the bottom and pushed the snow UP the driveway. Sure, a skid steer could do that too, but having a tractor sizable enough to do that is significant. I don't have chains for it, either.
Since I can only afford one machine right now, it's definitely a tractor. I don't have woods to navigate, just about 30' deep of trees along 2 of my property lines. My big tractor wouldn't navigate woods too well, but at nearly 6000# and R1 Ag tires, the woods would flatten pretty easily too

The FEL is good for lifting 1800#, so it has the capacity of most smaller skid steers anyways.
Don't get me wrong, I'd love to have a skid steer. The funds don't allow it at this time, and I really want a Takeuchi when I finally get one. One day...
Tractors vs. skid steers: they're two different machines. Their functions can cross in a lot of applications, but one is not better than the other in all applications. Earth moving and heavy lifting will almost certainly always be a skid steer application, but working the ground and the hat tips to a tractor. Both can move logs either by skidding them or via a grapple. The benefit of a tractor vs. a skid loader for moving cut/split firewood is that I can put the wood on the FEL and the 3 pt hitch to the tune of about 1.5 cords at a time.
