Which heatsink is better at cooling the P4?

[Bad Dude]

The contestants are:
-Swiftech MCX4000.
-Thermalright SLK-800(U).

Noise can be an issue with the Thermalright SLK-800, since it's an all copper heatsink which might need a more powerful fan to blow the heat off. Since copper transfer heat better but dissipate heat slower than aluminum. Please give your experience and reasoning to your choices.

Actually, from what I have read, all of the Thermalright copper heatsinks seem to respond very well to low flow fans. People are getting pretty good overclocks with the SLK-800 and a Panaflo L1A.

Which one would least likely to break after multiple removal times?
Which one is easy to mount?

Thanks.

Their both bolt-on so I would guess their installation is similar (its a pain, I have the alpha pal8942). I would thing the Swiftech is less likely to break because the slk-800 has those fins that probably could be dented.

And, I think the Swiftech is a better at cooling and it can support a 92mm fan.
