cPanel Redirect or htaccess fiddling? Which for me?

[fjpoblam]

I want two simple things for my website content. Call it, sitename.com. (FWIW I have "Let's Encrypt" set up.) I want:

 

(1) When someone enters the names, in a browser, sitename.com or http://sitename.comor https://sitename.com, they should reach my content, and "sitename.com" or "https://sitename.com" should appear in the browser address as the result.

 

(2) When someone enters the names, in a browser, www.sitename.com or http://www.sitename.comor https://www.sitename.com the same result should occur as I have described in (1).

 

Can this be as well accomplished in cPanel Redirects as it can my fiddling with my .htaccess file? And would it be better to do one or the other?
