Man, i would recommend you Rogero's 4.30v2.0 for now.
If you really just want to play and enjoy online, Rogero's is pretty stable, simple and better for you, but yes, it has some brick reports. But think, Rebug is on 4.21, what means that, some incoming games may required the newer FW vers. and you have to wait for a fix, or update you're CFW.
said, it has the minor brick cases(i personally don't see a single post reporting bricks on Rebug 4.21 Rex), and it's a complex CFW with a lot of features, but if you're not curious or a advanced user, it will not make any difference to you.
You're on Kmeaw, so the only feature you will miss on Rogero 4.30 is the "install package files" function on you're XMB, but don't worry, just install the latest multiman before update and you'll be ok.
Do some search man, both of that CFW had their own tuts from their developers, following then you can update without any issues.
