Well RROD ended about three years ago although some users on this site don't want to admit that. But It was a huge financial burden to MS. However MS was able to handle the situation well by fixing consoles for free and extending warranties. This in the end gave MS a positive reputation to their customer service.
Meanwhile the financial damage done to Sony is still unknown. In the end the PSN failure and theft of information could be more expensive than the RROD, and because sony has handled the situation so poorly in the PR department their reputation is taking a greater hit than MS.
I think in the end neither company will be remembered for these problems in the mainstream. But in the gaming community Sony will take the bigger PR hit.
