They say the e-ink display has "Unmatched Speed, Never Seen on ePaper" so it would nice to know the actual refresh rate.

This is not an endorsement, but https://daylightcomputer.com/ claims 60fps, so that's the bar to meet in my opinion. Caveat: the daylight display is not true e-ink, but an e-ink-like LCD, IIUC.

Im confused, how is a different technology the bar to meet for a given technology?

That feels like saying “my car can go 60mph so thats the bar to beat for a bicycle”.

Whats the battery like on the daylight?

Both devices focus on readability and rely on a reflective screen. Both devices are monochrome.

This is like comparing OLED vs MicroLED. They're technically different technologies, and each has it's own strengths. The OP is saying that "Never Seen on ePaper" is like saying "The Best iPhone Ever"...
