The official guide :)
I spent a lot of time on it. Read it through and you're basically good to go.
If you prefer videos, the Laracasts series is probably the best starting point.
Coligo.io also has some nice tutorials.
Finally, more resources can be found at awesome-vue.
I'd say Vue is definitely easier to jump into than React, especially if you come from a traditional web development background (started with HTML/CSS/JS), because Vue components embrace what you already know while React tends to shove them away as lower level details and abstract over everything in JavaScript. That said, your mileage may vary. The interesting thing is that when you get into advanced level, there's in fact a lot of shared knowledge, such as build tools (webpack, babel, npm scripts) and state management (flux, redux, vuex).
