TMC2209 vs TMC5160


I am doing a build with a GSO 8" Dobsonian and working on sourcing my materials. I don't quite understand the difference between these two different stepper drivers. Could someone explain the difference or which one is appropriate for my use case? I went with the maxESP3 board. I am planning on using the 100:1 Nema17 stepper motors with a complete gear reduction on both axes of 800:1.
