Dude,CPU > SPU,Spu are only good at a few things wihle CPU can do everything,but the few things SPU do do there very good at.
The SPUs can be used for all kinds of game uses. Like Insomniac said, ideally nearly everything should run on these SPUs instead of the PPU (roughly the equivalent to a Xenon core).
At what kind of CPU uses do you imagine the SPUs to be weak? They are powerful and competent at all CPU related tasks. Of course they are simplified (yet far more complex than the bulk of past CPUs, sacrifices in terms of convenience not performance!) which requires more effort than is needed with PC CPUs (like is the case for the Xenon, but the Cell is more different and thus requires more effort) but also allows for far better efficiency.
256 obivously is alot because Red Faction couldnt even put the game on PS3 due to is 256mb and they pushed the 360 Memory to its max.
Every 360 game can be ported to the PS3 and vice versa, with enough platform specific optimisations every outspoken game developer agrees the PS3 provides well more technical potential.
