Ways of saying "We're better than you" in Cantonese?

[indecision]

Hello everyone, this is my first post here so I'm sorry if I do anything wrong

I need to know how to write "We're better than you" in Cantonese. My guess was:

我哋比你哋好好多

However, I also need it to sound kind of rude and bitchy, and I was under the impression that using "bei" to mean "compared with" had more of a formal tone to it.

I asked my Cantonese friend and he said:

我哋好gwo你哋 (< also, what character is used for "gwo"?)

But how would you write or say this if you were trying to sound nasty?

Thank you for any help you can give me!

I would insult the other instead of saying good things about myself.

Something like: 咁[For added rudeness: 9]咋架你哋。

But if you insist: 我哋好[for added rudeness: 9]过你哋多多声啦。

Thank you very much!

I'm still a beginner though, so could I ask would "多多声" in that sense mean "better reputation"? Also I'm not sure what you mean by "For added rudeness: 9" (though i'm guessing you're referring to the tone number)?

多多声 is a slang meaning by very much/by a big margin. 9 is obscenity. What was the situation where you wanted to say that?

Ohh, I see!

I'm decorating a shirt for a friend and she wanted "We're better than you" written in Cantonese. It's her team's shirt so she wanted it to be kind of rude and bragging.

Both of the phrases I suggested wouldn't work well in your situation. I have to think about it. Let's see if other people have any suggestions.
