I heard about UniKeep binders on this forum and was interested so I tried 5.

For info see unikeep.com


Pros:
- pages lie flat in a closed plastic case for dense stacking
- similar to a binder in a slip case but lower cost
- you can customize the cover art

Cons:
- 9-pocket Ultra Pro pages fit snug in case and the case has support bars and catches that rub the top & bottom edges. I worry that if cards slid up towards to top open edge they would get damaged (less an issue for archiving).

My current preference is for Ultra Pro (or similar D-Ring office binders in old USPS Flat Rate boxes cut to size as the slip case.
