Positive

• Rock is faster
  
• Rock has less errors
  

Negatives

• Rock does not get as many sources
  
• Rock does not get all applications
  

I personally have both Rock and Cydia. For those who use Icy should either go to Rock or Cydia.

What is rock exactly? I only have cydia and the only bad thing is that it takes a while to load sometimes.

Why as a negative for rock it says less sources? You can add more yourself. I prefer rock just because it's faster for me, but I have 3.1.3 jailbreak so cydia is alot faster than before.

i use cydia not rock i used to use rock and it almost crashed my itouch idky though

And cydia is a rock app

i personally use..cydia.
i have tried rock so my opinion is basically worthless

I like Rock as it is faster and I have less problems with it.

I like cydia because it is very stable and backed up by a stable community.

I didn't know Icy was still around?
I use rock more often but I have cydia just in case I need it to download something Rock is missing.

I use rock more frequently than I use cydia. I just start getting frustrated due to the huge load time that cydia has.
