Not sure on TJM but from what I was shown of the ARB bar I thought it had some good ideas and design. ARB make the genuine Nissan.
One thing that I really liked was how they put in a space in the rh wing for the winch solenoid and a socket so as to connect the controller. Keeps the whole lot out of direct weather and is neat. One thing I don't like about the genuine Nissan is the flimsy recovery points down low near the chassis mounts. Pull them straight on and they should be fine. Anything greater or less than that and I expect them to bend over as they wave no lateral support.
