Has anyone done a comparison of Perforce and StarTeam.

My limited evaluation of StarTeam indicates that it is reliable and fast like Perforce (although I have not done any benchmarks to test either of these). StarTeam's user interface is much more extensive and has lots of built in
features like defect tracking and Lotus Notes like discussion groups.

What StarTeam doesn't have is the atomic change submission that Perforce has.
They also only work on the PC (with the exception of a limited functionality Web interface).

If you have more information about how the products compare, I would love to see
it.
