Should I include CSS and JS into my xml file or not?


Greetings everybody!!!

After disabling of Google Drive hosting, I am thinking to put all my CSS and JS files back into my blog’s XML code. But, before I do that, I would like to know, is it better-faster for my blog, to have CSS and JS into my XML code, or should I search for an other place to host those files? Cause I am reading some articles, generally on internet, and I am confused!!! Others saying is better to have CSS and JS into XML, others saying is not!!! So, please help!!!

Thank you in advance!!!
