What do you like best about Blender?

I am from Russia and I want to create a fan-video (3d motion design) about Blender with a duration of about 20 seconds, now I am doing analytics / preparation.

I want to collect the main interests of fans of this program, I will be grateful if you can tell me what your favorite functions or features. What are the advantages over competitors? Everything you love about Blender.

Personally, i like it that:

Blender is the FREE and open source 3D creation suite.

It have wide range of possibilities—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, video editing and 2D animation pipeline.

Cross platform - It works in different OS: Windows, Linux, MacOs

Hope for your feedback.

I apologize if I made grammatical mistakes, google translate.
