John Carmack, the co-founder of id Software, has gone on record as saying that the PlayStation 3 has more raw performance power than the Xbox 360. However, he admits that it comes at a cost, as it's much harder to tap.
Speaking to NowGamer, Carmack said: "Now the PS3 in particular, and this has been passed over many times over the years, but the core architectural decisions of having the cell processors versus additional symmetric processors makes life more difficult, unquestionably it's harder to develop for those there.
"You have to use a separate tool chain, the debugging is crappier, and all this. The upside of that is, there is more raw performance for computing there than there is on 360," he continued.
Carmack did state though, that despite these challenges, it's far better than working with the PS2 and the Sega Saturn: "It's a great time to be a developer. It's not like working with the SEGA Saturn or the PS2, where these are really kind of quirky, cranky, architectures that are not, well, architected, I would say."
