Skid steer has a Dozier beat all day. Might not push huge trees over but it is the best at probably 99% of clearing desires. This machine with a tooth bucket is great for cleaning debris, clearing small trees and brush, digging dirt, road grading, water breaks,......... you can move it with a pickup and 12k trailer. Rubber tracks. I could go on but I have been clearing and doing site prep for a number of years. This achine combined with a small track hoe of similar size are dynamite. If you have a large enuff trailer, both can be hauled. Plus a skid steer has a plethora of attachments.
I would hate to know I had to use a skid steer to build and crown roads compared to using a dozer.
The OP has several options depending on what his budget and time frame are which I havent seen mentioned. Is he talking about having $30k to spend on equipment, or $130k.
A good operator will do more in a week than a inexperienced one could do in a month. Ive worked on all types of dirt and construction equipment and played on it as a weekend warrior for a lot of years and I still cant do what someone who runs it every day can do with it.
