A few weeks ago I accidently caused an uprage on the Miranda Cosgrove page where I said that she was horrible at singing live. Someone (I'm not gonna name any names) called this Miranda "bashing", and ended up pulling the idea of Jennette singing live into the conversation. A little while later, a similar thing erupted on the Jennette McCurdy page, where someone else said Miranda was better than Jennette.
iCarly wiki has been working very hard on preventing ship warring. For a while warring of any kind died down. Then this started.
Jennette and Miranda are equally good at what they do. No one is better than the other.
