Levaquin or Cipro for upper Respiratory Infection / Bronchi?

I came down with an upper respiratory infection/ Bronchitis and 101.4 fever over the weekend. I have refills on Levaquin 500mg tablets and Cipro 500 mg as well. I can't get a hold of my Doctor this morning and really need to start taking something today. Which Antibiotic will help me more the Cipro or Levaquin? Thanks for any info.
