I mean I guess there are more noob friendly distros than Debian [ there was a time when all I saw was Ubuntu around me and it's ubiquitous Unity DE was instantly recognizable to my eye] but chances are many of them are ultimately based on Debian itself. Mint's main ISO is based on Ubuntu [and indirectly Debian] whilst they also release a LMDE [Linux Mint Debian Edition] as a fallback variant directly based on Debian. I guess Zorin OS or elementary OS are also decent but they also seem more like heavy reskins to me than anything else.[Zorin has a Windows like feel to it].
