IBM Out in Front Further?

I don't work with Unix servers, but I've always heard that entry servers using the Power4 processors were the best. From The Unix Guardian:

As I said when I went over the high-end and the entry Unix server markets earlier this year, without any doubt, IBM has been an increasingly dominant factor in the Unix server business, across all form factors and SMP scalability, since the Power4 processors debuted four years ago. IBM is, in fact, arguably the main reason that the Unix server business has seen any growth at all.

Now, as the table with that article shows, the 2005 pSeries kills the competition in their workload tests. I'm curious though about other server solutions (large or small scale) that Slashdot users may work with or know about. What about Unisys or Hewlett Packard scalable multiprocessor (SMP) solutions? Has anyone used Unix on these? Is it not recommended because of the chipsets or the way the processors are built?
