They're pretty good, but you can find other good trackpads too. The main thing about Apple is that their trackpads are consistently pretty good, while with other brands it can be hard to figure out what you'll be getting until you try it yourself.

There's also software component. It has improved by now, but early libinput was giving some good trackpads bad rep.

I wish the trackpad on my macbook were smaller, because my thumbs constantly hit it and smite me into a different reality.

While typing?

Yes.

Interesting, I feel like Apple's palm (I guess thumb?) rejection has been working pretty good for me. In fact I am pretty sure as you type the cursor is completely disabled?
