I would get it for any laptop, but not for any other Apple product. There is one part in my laptops that are almost sure to need AppleCare. It's the battery. My usage pattern kills all but the most robust batteries. For me there's at least a better than even chance that my battery is not going to last the full three years.
Besides that, I found Apple to be amazingly generous in what they were willing to fix under AppleCare. I had a 2016 MBP that I sold. Prior to selling it, I brought it to Apple to get a new battery and have a display discoloration problem fixed. They sent me back a machine with a new top case, new bottom case, new display, new logic board, new GPU, and new Thunderbolt 3 ports.
I was surprised they replaced the GPU, logic board, and ports. I suppose they may have been connected to something else or they just detected something odd and swapped them out without me asking. Either way, I was stunned to turn in a well worn laptop and receive back something that looked as good as a refurb unit. The ports on that unit were loose from day 1, but the replacement ones were tight and had snap.
Yeah, I'm a fan of AppleCare.
