Ranked in these QuestionsQuestion Ranking
Pros
Pro Great starting point for kids
Scratch was developed specifically for kids ages 8 and up as an exciting way to introduce them to technology. It's designed to be easy to learn, but still provides good depth in computational thinking.
Pro Visual
Code is represented as visual building blocks that makes it easy to understand how a program is put together.

Pro Easy to learn
Scratch is designed to teach computational thinking rather than focus on specific syntax. It was designed specifically to be easy to learn for anyone over the age of 8.

Pro No need to be able to type

Pro Can be used to create games
Pro Highly structured
The language is highly structured. Therefore, it gives you the essentials of how to think like a programmer and teaches you good programming practices from early on, so you could write clean, working and readable code in the future.
Pro 3D support
Since pyglet is so tightly woven with OpenGL it allows the support of drawing in 3D.
Pro Cross-platform
Works with Windows, Linux, and OS X.
Pro Written in pure Python
A small advantage, but being a core Python developer, it may be the best to stick to the roots and develop with pyglet as it is able to compile using other Python interpreters.
Cons
Con Does not teach you programming
Learning Scratch might help you if you have high difficulty with logical thinking. However, starting with a proper programming language, especially an easy one, will give you the benefits of starting with something like Scratch and everything else.
Con For kids, so don't even mention it in a job interview: it makes you look like a noob.
Con Won't get you a job
Scratch is not a language used in the workplace. Instead it teaches computational thinking, helping to create a foundation to aid in learning other languages.
Con Strange OOP
Scratch has a very strange implementation of OOP that is sprite based, and will become very confusing when you move to other languages.
Con Small community/popularity
There is a decent amount of documentation and API to go along with pyglet, but in terms of community support there seems to be very little.
