Which shader editor should I buy or use?

I was hoping to use ShaderFusion, but I did not succeed, which shader editor should I invest my time and maybe money to learn to develop shaders?

ShaderForge became free recently. The developer won’t continue developing it further as Unity 2018.X ships with Shader Graph (check rakkarage’s link above), which is similar to current available Shader editors (e.g. Amplify Shader Editor).
