Kinesis are king. But if you want a cheaper option, Microsoft Sculpt Ergonomic or whatever it's called is quite good, even though it's not properly split. The halves are angled so that your wrists wouldn't be crooked.

And when I inevitably break the key mechanism trying to clean inside, I unpack the old reliable MS Natural 4000 and clack away again.

I remember when I was a teenager and those things were all the rage (mid 90s). I wanted one just because they were alternative.

Fast forward a whole bunch of years and I'm pilfering the supply closet at work, and happen to stumble upon a slightly dusty, but functional and genuine OG Microsoft split keyboard. So of course I just had to.

Let's just say that keyboard is back collecting dust in that exact same spot. The ergos of it were okish, like your hand naturally rests like that. But even just that little difference of layout messed my muscle memory up way too much. And you are right, hitting some of the function keys was too alien.

I love my glove80 but it's not without a learning curve

Kinesis Freestyle2. I've had mine since COVID and still love it. They have both Mac and PC key layouts, including function keys.

Edit: I'll add it's an "at home" keyboard for me. If you need to travel with it frequently, it's not super mobile.
