Vive - the most reliable accurate tracking.

Tundras - in theory are good as vive, but have big QA issues, a lot of people get a bad unit and then spend months on RMAs

Slime/any other IMU based - inacurate tracking, legs will feel floaty/slidy, depending on IMU used and activity level you WILL have to reset tracking every 10-30 minutes.
