I have white, black, titanium, and copper. The only atomizers that are not the joye brand are from innovapor. They were black, but the paint came off very easily, so they are now silver. The performance on them are pretty much all the same. I have not had one die on me and it has been about
three months in a steady rotation. Also the non joye atomizers are a little bigger and the cartridge is very loose. So, if you mean brand as in manufacturer, stick with joye. Brand as in labeled with a different name, they're the same.
