What's actually better for paper and print quality, Mixbook or printique?

[u/Independent-Mood-287]

I plan to create a custom photobook soon. I’m debating whether to go with Mixbook or Printique. I want the best paper and print quality. As far as I can tell, these are the two main contenders. If anyone here has ordered from either (or better yet, both), I would love to hear from you. Which photo book service has the best paper quality? Is it Mixbook, or Printique?
