Aperture 61 vs Ferrule 75

Both tested here, side by side: measured sound, latency and typing scores for the Aperture 61 and the Ferrule 75, and which one to buy.

The short answer

The Ferrule 75 scores 1.6 higher overall and costs $89 against $45. Almost anyone buying their first good keyboard, and most people buying their third. Buy the other one if: someone who wants a hot-swap 60% to modify, and considers a stabiliser tune part of the fun rather than a defect.

Shape and footprint

Aperture 61

60% — 61 keys, 15u wide. No function row, no arrows, no navigation cluster. Everything above the numbers is a layer.

Ferrule 75

75% — 82 keys, 16u wide. A real function row on top of the 65% shape — the densest layout that still has F-keys. Highlighted keys are what this layout adds over the next size down.
