For my Radeon based setups, the open source driver runs much, much better on Compiz than kwin. I defiantly think there is a lot of room for performance improvements in kwin. The ATI drivers are much faster, but tend to be less stable. Kwin's feature set is useful enough that I tolerate the less than flawless performance.

I've got a Radeon card running on the open source driver, and installed the new beta yesterday due to a bug in the stable version of Archlinux's Akregator (true story), and it does seem a bit smoother, especially for the exposé-like effect, but still not quite as fast as compiz.

You can always run KDE with compiz as the window manager.

Go to System Settings --> Default Applications --> Window Manager --> Use a different window manager

I think this requires you to install a helper application (it may be called kde-compiz) which will also install compiz itself as a dependency.

Having said that, the Radeon drivers are improving very rapidly:

This is great on Arch Linux, which has rolling updates. In general Arch will pick up new stuff like this within a month or so. The Radeon drivers have already improved markedly twice this year, and the default (on Arch Linux anyway) has now switched from the classic mesa driver over to Gallium3D.

Yes, I've run kde with compiz before. I prefer kwin and all of its useful composting tricks, like the psuedo aero snap.

I'm thinking/have thought about moving to arch. I'm just a bit afraid it will end up like gentoo. I'm okay with being a few months off of the bleeding edge.

I've had the opposite experience, or rather, KWin with OS radeon driver runs quite smoothly with a few minor exceptions with some effects I don't use. If I put it on XRender instead of OpenGL, it's smooth as butter (except for the vblank synching, of course).
