Choose this fork only if you specifically want a stable snapshot. For most adopters, upstream is the better choice because it is more current and this fork adds no visible capability.

Choose this fork only if you want an almost unchanged copy of upstream and are comfortable being slightly behind. If you want enhancements, curation, or active maintenance, upstream is the better default.

Choose this fork only if you want a near-raw mirror and do not care about freshness. If you want the most current textbook archive or any added organization/workflow, upstream is the better choice.

Choose this fork only if you want a math-only slice of the textbook collection and do not care about recent upstream updates or non-math subjects. For most adopters, the upstream repo is the safer default because it is larger, more current, and better maintained.
