A RROD kills your entire system so you can't play games. And has been a consistent problem overe the entire course of the XBOX360.
PSN just doesn't allow you to utilize the online features of your PS3. But you can still play single player games. And its only been about 2 weeks of downtime, which is less than whatyou'd be down sending your XBNOX360 in for 'repairs'. Especially if your XBOX360 has died 3-5 times like many people.
I don't know why people keep making this thread. 2 Weeks vs 6 years of problems is pretty easy to compare.
