A fixed split shape, or an independently certified adjustable design
Do you want to try a split layout, or invest in a design independently certified for posture?
Both keyboards use a split layout to change hand and wrist position, but only one carries independent ergonomics certification and adjustable tilt — the other keeps things simple and wired.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
Take the Perixx to try a split layout for the first time, wired and fixed — after checking the layout on the US page.
No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.
Take the Logitech for adjustable tilt, wireless flexibility, and independent ergonomics certification behind the design.
Expect to, with either: moving to a split layout usually means a period of slower, less accurate typing while your hands adapt. Trying a split keyboard for the first time covers the first weeks.
Both type on a Mac, but neither listing we read states a Mac layout: the Perixx is British QWERTY and the Logitech states no layout. Do ergonomic keyboards work with a Mac? explains the modifier keys and regional layouts.
Wired · fixed split 3D shape · integrated wrist rest · UK QWERTY · 485 mm wide
A wired, full-size split keyboard with a fixed 3D shape, an integrated wrist rest and 7 multimedia keys, 485 mm (19.1 in) wide — in the British QWERTY layout on the listing we read.
Best for: A first split keyboard, wired, for someone who wants to try the layout before anything adjustable.
Curved split · 0°, -4° or -7° tilt · USB receiver or Bluetooth · US Ergonomics certified
A wireless curved split keyboard with concave keys, a padded wrist rest and feet that set 0°, -4° or -7° of negative tilt — the only keyboard in this hub certified by an ergonomics organization.
Best for: Someone committing to a curved split layout who also works standing, where negative tilt matters.
