The notable differences are the thickness of the tops. You can't use Festool style of clamps on a top that thick as the Armor tops. The Armor dog holes use canted posts to lock some clamps and accessories in. Over time those holes will enlarge or distort because of that accuracy will not be a long term asset for the Armor table tops.

I got a couple of Armor clamps to use with my current workbench. They work OK, but they are not my go-to clamps by any means. I worry about the canted, ribbed stem and the effect on the dog holes, but really the reason that I don't use them is that they just don't have a smooth, solid feel to them. On the horizontal clamp, the head seems to want to cant a bit when applying pressure. ...And, I'm not a fan of holddowns in general.
I got the Armor clamps before I got my MFT and started using Festool 20mm hole accessories - cogs, clamps, clamping elements, etc. Since then I've started on a new workbench that has MFT styles holes. I've even started using the Festool clamps with my old workbench. For 3/4" dogs and fences, I've found that I like Veritas stuff the best on my old bench, but for clamps I find that I'm reaching for the Festool or similar Bessy clamps first. I've also gotten a couple of Veritas 20mm accessories, which I also like for certain tasks.
At any rate, I never reach for the Armor clamps any more.
