Tunngle or Hamachi.

I am kind of interested to know why people prefer Hamachi over Tunngle and vice versa.
I figure it might be good for those who are skeptical about 3rd party lan oriented programs and are looking to see what the key differences of both opinion and fact are.

I personally like Tunngle better as I found Hamachi to be sort of annoying, vs. Tunngle does alot of the work for you. However, thats just me?
