Diamonds can have a little over twice the thermal conductivity of silver, so it has the potential to perform better. I'd want to see some tests though, because that's assuming pure diamond vs pure silver. Grinding the stuff up into tiny chunks and suspending it in some kind of goo is bound to change its thermal properties... not to mention how the stuff is applied to the chip.

Well let me tell you, I used AS5 for years, great stuff, still is, but last year or so I switched to, on my CPU, "IC Diamond". Compared to AS5, my temps did drop about 3°C, and I imagine it would be more if I had a true flat contact surface instead of the direct heatpipe touch cooler I have (I'm sure Steveo could give you better numbers because of his liquid cooler). My feelings on this are that yes diamond-based TIM's are better than silver based TIM's, and my experiences show that it is, but there are a couple of caveats to diamond TIM, such as they cannot be used on GPUs due to the small particle size (which does etch surfaces). But if you think about it, the price difference is pretty small so you might as well get the diamond, I don't think you'll be disappointed.
I have K9, few weeks ago I did it. It is harder to remove than AS5, no doubt due to the smaller particle size. What's bad is that you'll clean it all off with alcohol and a rag to where it's nice shiny copper, then you'll rub it yet again and even more will come off. Ended up using about a quarter of a container of 50% alcohol (local stores don't sell 91% anymore for some reason).
