My experience with mac is that yes it looks like to have longer battery life with less fan noise sometimes, but it might be by tricking you into a worse user experience of your machine.

For example, you computer to always go to kind of sleep when it is not necessarily what you want.

Like with the memory, you will not see app crashing upfront, but at some point macos stops all the other apps when you switch app. And like going from a web browser window, to a pdf, and back, or from a browser window to another, you will experience something like a 1s delay between your click and the window showing up from being minimized.

I have not had this experience on my MB M2 Pro, although Safari can be quite sluggish.
