Is audit better than tax? Who makes more money?

I am an accountant with five years of experience, but I only worked for a CPA firm for a year. Now I ped two parts of CPA exam, and I need to move on to Public firm to get my CPA license. I haven't decide where I should land on, taxation or audit. I would like to know which one is better for the long run, and who makes more money, an auditor or tax preparer? Another question I would like to add is...is it better to stick with a public firm or is it better to move on to private after gaining a few years of experience with a public firm? I am a minority and I don't know if that affect my career life.
