What weapon is best w/ Mirage?

Hi all, I'm kind of new to the game and I was wondering which weapon I should get? I know it comes down to playstyle but I'm having a really hard time deciding. I'm low level, the farthest I have got is Jupiter, so I want to know some good starting weapons as I've been playing Excalibur the whole time. Should I go with a Burston, Bration, Paris/Cernos?, or something else? Please give me some advice :)
