Your setup may be ergonomic, it really depends on the whole picture. How are you sitting/ standing. and how are your arms positioned in relationship to your position,
Two of the most comfortable keyboards I’ve used have been the Tex Shinobi and the SteelSeries 7G with it’s included wrist wrest, both in their flattest position, which still have a slight degree of tilt, but I also position my arm wrests, so my arms are slightly extended out and angled up ever so slightly.
