Ryanpower2 550W or OCZ ModStream 520W Modular PSUs?

[Judaeus Apella]

Both are modular, both are recommended on this site, both have good reviews. What I wanna know are things like this:

Do they have PFC?
How much protection do they offer my system?
Whats the customer satisfaction rating?
What kind of reputations do these companies have?
Whats the quality of their fans and heat sinks?
How much power do they offer on each rail?
Etc...

I know I know, but a lot of people here have experience with them and thats what Im looking for. The opinions of consumers.
