Klipper

The "best" firmware is if you want to push the mechanical limits of the Sapphire Pro. The printer's linear rails and CoreXY structure are built for speed, and Klipper is the only software that truly unlocks that potential.

Backup Your Settings: If you can, note down your current E-steps (extruder steps per mm) and Z-offset values. These may reset during a firmware flash.
Check the Screen: The Sapphire Pro usually uses a standard TFT screen. Ensure the firmware you download is configured for the correct display type (usually REPRAP_DISCOUNT_SMART_CONTROLLER or similar in Marlin config).
Inverter Cables: Some older Sapphire Pro units had inverted Y-axis cabling. If you flash new firmware and your Y-axis moves the wrong way, you can either swap the physical plug on the motherboard or invert the INVERT_Y_DIR setting in the firmware source code.

Run PROBE_CALIBRATE for Z-offset.
Run BED_MESH_CALIBRATE.
Run TUNING_TOWER for Pressure Advance.
Run SHAPER_CALIBRATE for Input Shaping.
