I’ve used the second (sans baffle) and the 3rd.
The two bucket deal stirred up enough dust and chips from the bottom bucket that I never got it over 1/2 full. The junk lifted up and ended up in my shop vac. The baffle might help with that, hard to say. Cheap enough to try if you have some scrap wood, a couple buckets, and a hose to try out.
The dusttopper works great, especially for the price. Got that one 3/4 full before stuff started going to the shop vac. I consider it a bargain because it comes with a hose, too ($10 value at home depot) and doesn’t require any work or parts (beyond the bucket) to assemble. I think it was closer to $40 when I bought it, though, so YMMV. As noted, it is also more compact and easier to locate/relocate. Easier to empty, too, just because it’s shorter.
In both cases, I’d recommend a quality filter bag because fine dust still gets through. I had a ton of it clump up on my wall by the vac outlet before I realized just how much. I ditched the pleated paper filter.
