4th Gen Lucario or Gallade

I'm using level 43 Gallade and level 30 Lucario i'm gonna using one of them to beat Cynthia's Lucario wich should i have?

I used both in my original Diamond team alongside Infernape. Despite the fact that it gave me three fighting types, I would totally do it again. I used to whomp on my friends a lot with that team.

If I had to pick between the two, I'd probably go with Lucario. Then again, I'm biased over my love for Rasengan Aura Sphere.

Well... it depends on you but if I have to choose between these two Pokemon, I would go with Lucario.

Got a shiny Gallade via GTS once so my bias is Gallade. 8)

well if i had the option to go with furbait™ or a skinny, fedora wearing white knight...
i'd probably go with the white knight.

but seriously tho, if your gonna pick any fighting type, pick gallade
