The two machines are not really in the same ball park. Timbersled is nice, easy to ride and great for boondocking threw the trees.
In stock form a hawk will trench to china, a Timbersled has very good flotation, and is much more nimble than a hawk, until you get to speed.
A well set up hawk will leave a bike kit in the dust.They carve like a jet ski and will rip if you give it a chance. They are not easy to learn to ride, but once you do there is not really a comparison, they are just two different animals.
Talking to bike kit owners who have no experience with a hawk will get you a biased answer. Many Hawk owners, myself included have quite a bit of experience on both. They both rock in their own way.
I say get both.
