IBM big iron is a thing of beauty. There is nothing ill-advised in pushing a platform that's comparable to it in the good parts, and lacking the icky ones is a huge plus.
And it's a shame POWER is soooo expensive. But, then, so are high-end x86 and ARM, so I guess it's not that it's expensive more than I'm not paid nearly enough to have one. And, between buying a high-end POWER box and a yacht, I'll always take the second.
