I mean, ultimately it's gonna come down to personal preference.

For me, I kinda went all out... I use 1 of these per set, with these pages. Love it.

In the past, I've also used this binder as a cheaper alternative with the same binder pages as above, and for MTG I've also used this which was nice for 4-of playsets, but less of a fit for 3-ofs like FaB has.
