What is the best guitar for a beginner?

Classical guitar, imho, if you’re thinking about learning guitar.

Wide neck, so easy to see when your fingers are supposed to be, whether you have little skinny kid fingers or big fat hand sausages. And nylon strings are so much easier on new guitar player’s fingers. No need to plug it in so you can play it without an amp. Makes a pleasing sound right from the git-go. Relatively inexpensive- you can get a quite decent one new for about a hundred bucks. Looking at some of the other answers though, I can see “easy” means different things to different people. “Playability” is certainly the key here and that means a nylon string guitar to start out, to me anyway.
