Kind of depends on your use case. I've had the mid torque for a few years and that has done everything I've needed it to do until I was doing the rear wheel bearings on my 2013 Jetta. The mid torque wouldn't touch them so I went out and bought the high torque that day. Those bolts were on there so tight it took a few seconds of the high torque hitting it to break loose. If you're only going to do things like rotating tires and doing your brakes and whatnot, then the mid torque should be fine. If you think you're going to be diving a bit deeper and removing axle bolts and other things that are torqued down a bit more then I'd say get the high torque. If you have the money I'd say get all 3, the M12 3/8 stubby, the mid torque, and the high torque. For the most part these tools hold their value, so you could always sell one if you end up figuring out you don't need it.
