Not true. Google's ROM is optimized for certain uses, mainly just general use. Different custom ROMs are developed for different types of uses.
One reason there are no best ROM threads allowed. Different users prefer different ROMs because they use their phones in different ways. It is also part of the fun of experimenting. You can see how different ROMs react to your personal usage and most people usually settle with the one that fits them best, except flashaholics. Had my phone less than a month, went through about five ROMs, 4 custom and stock. Finally settled on slimkat as I like the features.
This also holds true for kernels.
