At a Glance
Every axis is scored out of 10 from the catalog specs below. The scores are relative to the products on this page, so a 10 means “best of these”, not “perfect”, and two identical columns mean the catalog genuinely cannot separate them. Axes the catalog holds no figure for on both sides are left off entirely rather than guessed at.

| Passthrough | 10/10 | 10/10 |
