TMC2209 every time. Reasons:
1. Silent at any speed (StealthChop)
2. Sensorless homing if you ever want it
3. UART config — set current in software, no jumpers
4. Built-in thermal protection
A4988 / DRV8825 work but are noisier, hotter, and don't do sensorless homing. Cost difference is ~€2/driver. No reason to pick the older ones for a new build.
