I am using a Matias Tactile Pro, which is similar to that old mechanical IBM keyboard with an layout with a lot of symbols (which might be nice if you do math and data science). It is heavy, big, and super loud but I really like the sound, and it feels just good. I have good experiences with it, using it since about eight years. Has also two USB ports which is useful for charging stuff and gadgets.
I have to warn about the Matias Quiet versions though - they are not durable and keys are failing quickly. Unbelievable the difference in quality.
Many people make a fuss about ergonomic keyboard layouts. I just do not understand why. My recommendation is this:
1. Chose a layout which is useful for your language(s) and programming - best layouts for this are often from multi-lingual countries like UK International (https://en.wikipedia.org/wiki/QWERTY#United_Kingdom_(Extende...), or Canadian, or such. (Some national layouts like German are horrible because keys like '{' or '}' cannot be reached in an ergonomic way. It might therefore be better to put rarely-used regional characters on dead-keys, which is exactly what UK International, for example, does.)
2. Learn to touch-type on that one layout, and stick to it.
Anything else is very unlikely to ever give any return in time you invest. Especially when you are coding - the key that is used most often for code is empirically the "Delete" key, and that's for a reason.
