I can second the ARB a mate has one on an SR5 and up the cape last year it was tough as nails.
I can also vouch for the TJM T3 bar (similar to ARB Sahara) - I just put one on the Prado and so far it is great. Only disappointment is that LED Parker's are an additional cost option with TJM.
Not everyone agrees, but I had 2 Ironman Protector bars on a 2010 Triton (first was replaced under warranty due to rust). I did not like it. In direct comparison to the ARB and the TJM it seemed weaker in construction, the design and the approach clearance under the wings was too low and it used a chassis extension mounting system to attach it. No matter how hard we tried or how many times it went back, we could never get the bolts tight enough to prevent it tilting forward on rough tracks and winching. Heaps of people love them though and I was told the way they attach to a Toyota is different to the Triton. That was the experience I had though.
Here is a Pic I have posted previously showing the difference in the approach angle from the Ironman to the ARB bars.
Hope this helps.
