I don't know anything about those drivers, and I'm not an expert on the subject of drivers.
I know from reading on the forums that the TB6600 drives, and ones similar to it, are garbage....there is always someone complaining about them or trying to get them to work. But I don't know anything about the CW8060.
My personal view is to buy either Gecko, Leadshine, and now I am thinking about adding Trinamic to that list. It's just not worth the hassle, or risk, IMO, to get a bad driver.
For my 3d printer project, I have decided on Trinamic for any stepper motors, but may use leadshine AC servo drivers as well. I'm not sure. Also, the Trinamic driver you are using was integrated by "Big Tree" but I might use a Duet 3 board with integrated Trinamic drivers. I don't know how this relates to the overall quality of the system, comparing Big Tree with Duet, when they both use Trinamic at the core.
That's pretty cool! Nice comparison videos! Hey, you've got rotating nuts! Too cool! How fast can you push this machine? Have you thought about changing up the gearing to make it faster?
Smoother or quieter? I am guessing that the movement is better in general.
Stealth Chop mode reduces the torque?
What would be great to see is a comparison where, using the same power supply for each driver, you bump up the speed and acceleration of the machine to see which one starts missing steps first. That could be another good comparison of each driver / mode.
Also checking the temperature of the stepper motors when idle or after a period of movement would be a good comparison.
Smooth or quiet? My understanding is the Trinamic drivers are the only ones that are so quiet. It might even be proprietary.
The Gecko drives I have would sound like they were playing midi music when I used them. I am guessing Leadshine is in the same group. I think many people started buying leadshine because they are a bit less expensive than Gecko Drives, provide some different options, and have good reviews about quality.
I only have experience with the G201X Gecko drives. And they are noisy, but not in a bad sounding way. It's like midi music, lol. I plan on using the ones I have on another project. I'm very happy with the Gecko drives. I never had any problems with lost torque, or loosing steps, or motor overheating, or anything negative. But they do make "music".
I think Gecko is a fairly small company compared to Trinamic, and they have served the CNC community well for many years. I certainly don't have any complaints about them. And Mariss is a regular on these forums.
But these newer higher voltage and current drivers from Trinamic might be a game changer. Particularly when it comes to driving Nema 23's, and not just Nema17's common in 3d printers and other small machinery, like photocopiers. Also, correct me if I'm wrong, but the Trinamic drives you bought cost $20 on Aliexpress? That's about 1/3 to 1/5 the price of a comparable Leadshine or Gecko product.
Some music played on stepper motors, just for fun (not my video, I just found it):
