If your domain is short, like Foxco.net Mcloren.com or JCP.com we advise using WWW because it:

• Looks more balanced www.foxco.net vs foxco.net — the second one looks like it’s going to tip over. Aesthetics matter.
• www. automatically creates a link almost everywhere — typing https:// is a pain even for those who’ve been doing it for decades, even before there was an s in https.
• Users referring to you around the web are likely to type www.your-short-domain.com and you want to be sure you’re catching all that sweet link juice.

Frankly speaking, we don’t think there’s really ever a situation where you need a long domain name, so I guess we don’t ever recommend non-www but if you must we’ve added the ability to go from www to non-www.
