Hey meizner , to be fair I haven't used the Quixel suite so I can't do a direct comparison, but you can certainly get great results from either one. I enjoy the procedural nature of Substance Designer and then in turn plugging those materials into Painter, but it likely comes down to personal preference or what specific project you're working on. I'm pretty sure both have free trials, so give 'em a spin and see which you like best!
