Articleship - Very Urgent

Hello,
          I am having an opportunity to choose to have my articleship in E&Y-Taxation or KPMG-Auditing. I am really confused where to go. I'll receive call from E&Y tomorrow and I have to answer him whether I am joining or not.
          Can anyone please tell me the advantages of going in Audting and advantages of going to Taxation . How ill each be helpful for Job after i become CA. I want to pursue the Finance Line in my career so none will help.
          Can anyone please tell me the future opportunies for both the fields Taxation & Audting.
          Thank You.
