I admit I could be wrong, but I have always heard that Power CPUs are pound for pound better CPUs. i.e. if you have a 3GHZ dual core in IBM and 3GHZ dual core in x86, the IBM will out perform it every time. This was especially true and pointed out repeatedly in the days when Apple used IBM as their CPU provider.

Apple changed to Intel because the PowerPC was dated and too slow.

The PowerPC was more powerful when Pentium 4 was the best CPU made by Intel... after that the Intel e AMD CPU's evolved and the PowerPC is the same CPU created ten years ago.

That's why the PowerPC is not even close the x86 today.

On the contrary, the Power line of processors are way ahead of the x86 machines.  Apple switched because IBM had no roadmap to shrink the processors and get thermals down, so when it came to the macbooks, Power processors made no sense.
