The following is from my peacock bass friend on hook strength testing. For golden dorado I have had great success with the Owner ST-66 which was not tested.

I tested 13 hooks in total.

Owner ST-76TN 5X 3/0 (0.305 Oz.)

Owner ST-66TN 4X 3/0 (0.245 Oz.)
Owner ST-66TN 4X 2/0 (0.170 Oz.)
Owner ST-66TN 4X 1/0 (0.115 Oz.)
Owner ST-66TN 4X 2 (0.080 Oz.)

VMC 8527PS 6X 4/0 (0.185 Oz.)
VMC 8527PS 6X 3/0 (0.140 Oz.)
VMC 8527PS 6X 2/0 (0.125 Oz.)
VMC 8527PS 6X 1/0 (0.095 Oz.)

Daiichi Bleeding Bait 7X 4/0 (0.185 Oz.)
Daiichi Bleeding Bait 7X 3/0 (0.140 Oz.)
Daiichi Bleeding Bait 7X 2/0 (0.125 Oz.)
Daiichi Bleeding Bait 7X 1/0 (0.095 Oz.)

============
Testing Method:

I kept things simple ... I tested all hooks at my max testing weight of 110 pounds of pull (except for the 1/0 sizes which were done at 90lbs) on a non-reinforced hook on the treble. What I mean by non-reinforced is each treble may have one or two of its hooks that is welded on and not part of the steel that is used to make the eye. I assume this to be the weakest hook and tested that.

Of note, the Owner Hooks are not of comparable sizes to most manufactures, they must use a different standard than the VMCs or the Diiachis. I assume them to be conservative and rated them at least one to two sizes larger than stated. You can also see this by their weights listed above.

Results:

The two 3/0 Owner hooks are beasts, but I really think they should not be considered for even the woodchopper front hook, due to their weights. The ST-76TN in 3/0 size did not even deform at all at 110lbs, while the ST-66TN had a slight visual deformation, but it was not permanent. BTW, they don't make the ST-76TN in sizes smaller than their 3/0 size.

I do like the Owner ST-66TN 2/0 treble. It had only a moderate deformation at full pressure, and only a slight permanent bend. It is a tiny bit shorter than both the VMC and Daiichi 4/0 trebles, but hook size seems a bit bigger than the VMC and Daiichi 3/0s (So i might call it a 3.5/0). It is light and strong ... good hook in the comparable 4/0 or 3/0 range and can be considered for the front hook on a full size woodchopper. Only con is it is the most expensive treble of its size you will likely find.

That's all the love I'll give for Owners. The 1/0 and 1 sizes failed miserably w/ heavy to extreme permanent bends.

Both the VMCs and the Diiachis are EXACTLY the same weights ... EXACTLY the same dimensions ... and have the EXACT same cone cuts on their tips ... If I was just judging by how they look under very close examination, I would say they are 100% the same hook ... just one was painted red. I tried to find some evidence that they could in reality be the same hook, where one brand was licensing it to the other, or they are related companies, but I didn't see anything obvious on that. Maybe they just use the same type of equipment .. who knows.

However, there was some slight differences in results. The 4/0 sizes came in about the same, but they rest of the smaller sizes were in VMCs favor ... but only by a bit (you can see that in the photo linked above).

Final Recommendation:
If price is not an issue and you need a large and light front lure hook, go with the Owner ST-76TN in size 2/0, otherwise go with the VMCs in any size. You could chose the Diiachi 4/0 for a front hook if you think the red color can help in attracting strikes, but otherwise VMCs are better and cheaper.

I did sneak in a test of the VMC in size 1, and it did surprisingly well with a 90lb force.
