Need Career Advice--Finance Industry?

I interviewed with Credit Suisse and Wachovia Securities earlier this week and received positive feedback from both. Credit Suisse is in the process of checking my references and Wachovia Securities would like to set up a second interview with me. Credit Suisse is a temp position with possible a possible permanent position at the end of the contract (Nov), is a TEAM environment, which I enjoy, and the interviewers (who are the people I will be working with) were great people who I automatically clicked with. Wachovia, on the otherhand, is a permanent position which has benefits BUT thing is, the Financial Advisor has a bad rep with the branch. The receptionist even told me that she was a 'tough one'. My first interview with her was 2.5 hours long and I was overwhelmed by her expectations in an assistant, yet alone, I'm scared to death of 'what if I don't meet her expectations?'.
I don't know what opportunity to take? HELP PLEASE?
