OK, I just looked into the Canopus stands, and just by looking at the wing nuts that hold the height position, the DW and Gibraltar both are going to do a way better job.
Both the DW and Gibraltar stands height adjustments clamp around the tube to hold it (and it's VERY secure on both brands).
The Canopus stands screw just pushes against the tube. That's gonna leave a mark (at best, eventually) and it's going to end up indenting the tube as you need more pressure to secure it in place over time.
The DW 7000 hi hat stand looks similar to the Canopus on the site, in that it's the same "style", but the DW looks to me as a lot sturdier (I've played it) than the Canpous.
The snare stand seems similar to the DW/Gibraltar with the basket and height clamp.
If it was me, I would go DW or Gibraltar over the Canopus stands for the height adjustment screw issue alone.
They may be fine, and if this is an "at home, set it forget it" thing, get what you like better, but for any gigging, I'd put the money into something that's going to last a long time without any hassle.
Just for "looks" of the stand, the Gibraltar might look "more vintage" because it doesn't have the black "tilter tightener" thing, and the cymbal space adjustment thing.
