Fitzmagic or Bortles?

League goes by Waiver Order, I’m currently 8/12.
QB: Alex Smith(Week 4 bye) home vs. GB

Should I burn my waiver for Fitzmagic or Bortles, or move up the waiver order and hope to get Bortles off FA.
Fitz would be the best play this week, but at the bears week 4. Bortles at home vs Titans this week and at home vs Jets week 4.
