Pros: You cannot beat the thermal conductivity ratings for this stuff. It outperforms pretty much everything on the market. It comes in a super-easy-to-use syringe that has about enough for one, maybe two installs. During use, this stuff doesn't cake on and solidify like most other thermal pastes do; so, removal is a breeze and doesn't require anything more than a cloth (nope, don't even need rubbing alcohol to get it off).

Cons: Pricey, but that's what you pay for raw performance.

Pros: Cannot beat the price. Each tube can get you through a couple CPU's, so the package can easily get you through over a dozen installs. Good thermal conductivity for the price.

Cons: Each tube I have opened has been pretty questionable on the consistency. Each one starts off very watery. I'd advise having a paper towel or something nearby to "prime" each of the tubes, otherwise you're going to squirt a pretty runny liquid all over your die.
