I've not tried them all, in fact I've only driven a Tesla on autopilot for a few 100 miles. However with 1 billion miles driven on autopilot and (IMO) relatively few problems it seems like it must be pretty good. I hear about accidents involving uber, waymo, and similar just about as often as Tesla, despite Tesla shipping 5000 cars a week or more. Granted only a faction of those are likely to have the $5,000 enhanced autopilot, still radically more miles driven than anyone else.
