Turnkey or Consigned PCB Assembly -What’s Working Better Lately?

For U.S.-based builds, I’ve noticed some customers prefer full turnkey sourcing to reduce risk, while others still supply their own parts to control cost.

In your experience, which model has been smoother recently?

Has turnkey become more reliable now that sourcing channels are stabilizing, or is consigned still safer for critical components? Would be great to hear perspectives from both engineering and procurement sides.
