1. When comparing next gen tech we typically compare it to the current generation device not older devices.
2. Apple TV HD has the same button layout as the Apple TV 4K. Did you mean the Apple TV 4, which was the same box as the HD but with an identical remote to the 4K minus the white menu ring?
One of the Apple remotes biggest strengths is that in so few buttons you never have to physically look at it. The menu button as a ridge, the volume toggle is long, and Siri has a bevel. This means any button you touch can either be identified immediately or in the case of tv or pause move your finger towards midline.
