Ctr to term. Should I jump?

Hey guys, currently a contractor, applied for a term job and received the offer.

However, it's a time limited NTE 3 years, but may be extended up to a max of 8.

As a term, I've been told that it does not give me any preference points, and that any future govt job I apply for, I'd be coming in as a Civilian.

Is this correct, and what do I do to minimize the impact at the end of the term?

Or should I stay on my current contract, for $15k more a year, and keep looking?

I don't mind the pay cut if I know I can use it to leverage into a Govt position in the future. But if there's no benefit, it's hard to justify.
