They are valid comparison point. Specially now. Antutu has always been very consistent benchmark and it gives you split scores. When you are experimenting with different ROMs and Kernels (specially when the device is new ), it gives you good idea where improvements are made.
Since 2.0 upgrade even Quadrant has been somewhat consistent (though still not as much as Antutu).
It might not be valid real world comparison, but its good way to judge or identify where the difference is as far as raw performance of ROM or Kernel is concerned and identify problem areas.
Some people love to hate on benchmark, I use them as additional tools to finalise my ROM / Kernel choice along with real world performance / behaviour and battery life.
