That's a mouthful. Using broad scope generalities lend little credence to your argument(s).
A well designed, engineered and fabricated bumper, such as Slee's Blueberry front bumper, spreads a recovery load over a much larger surface area including redundant, for recovery event analysis, mounting points to each frame section. Additionally this bumper, with its integrated winch mount, serves as a bridge between the two frame sections thereby further solidifying the structure.
Its apparent by your comments you have not done a direct comparison between the bumpers in question here.
Just say'n
I havent seen the slee bumpers first hand as im not in the US, so I cant say I can make a direct comparison, at least not first hand. I have had a lot of first hand experience with all three brands (ARB, TJM and Ironman) and have had COUNTLESS venezuelan made bumpers, the actual one on the 80 was custom made based on the Slee short bus by the way.
Im not implying that any of the bumpers mentioned are strong enough or not, but I think you underestimate the forces involved when trying to recover a properly stuck 4x4. The part where I said ive seen bumpers ripped off I meant in real life, not the internet, and ive had the chance to see this a bunch of times. One of those was a friend's 70 series' rear bumper which did not bend or break by itself, but rather ripped the threads off the chassis and bent the rear crossmember, which i think is sturdier and stronger than any bar anybody can make. This was a properly fastened and designed rear bar that he destroyed i might add. I also saw a guy that was aiding in recovering a vehicle, a bolt on recovery point (placed on the front bar) failed and sent a shackle complete with recovery point and bolts flying straight to his face, luckily he survived with no permanent long term damage, but this kind of recovery point is not the one in question though.
My point is, no matter how overbuilt, well designed or how many anchor points a recovery point has, anything can fail. And while Hoser says than more bolts is better and that is generally the rule, the more leverage you have on something the easier it will be to bend or break, and there;s no way a bar can have less leverage than a proper, chassis recovery point.
I will NEVER try to use a recovery point on a bar if I have proper chassis recovery points, not even if these are extremely well built and I will never recommend it either.. Experience has taught me this.
