There is no such thing as a cartridge or arm that is better at rock than anything else. That is a myth plain and simple. Electronics (including speakers) don't have taste and can't tell what music you are playing through it.
In short if its really good at jazz and classical its really good at rock too. That's how it is.
Now it may be that a particular recording reveals a weakness. That weakness will show up elsewhere guaranteed. Do as Doug suggests- its a good suggestion.
