Sure are, especially when you need more muscle than an ARM (though they're 
catching up). They still employ VERY proprietary access methods over JTAG, 
though, and there's not much in common from generation to generation. My 
understanding is that you can't even get the COP specs from Freescale unless 
you're a big JTAG pod manufacturer; I don't know what the other PPC 
manufacturers' policies are. It's a shame, because I really like the PPC, but 
it's hard to justify spending $3k on a debug pod for projects my size.
