Mac Software?

I am used to using acid pro for all of my songs, i recently got a Mac that im gonna be using does anyone know some good software for mac's and what it can do for me?

Logic Audio, TC Works Spark, Pro Tools....

Peak is a good two track sample editor too...TC I hear is a little bit better.

This is the a really good one too for laying out your programs/samples.
