Every distribution offers different things. I like debian sid for the simplicity and general software availability, but APT is something i still consider a bit clunky. I like arch because of its barebones philosophy - arch wiki helped me a lot learn about linux. I like gentoo - the wiki is awesome and portage is a great package manager. It was the first time I saw how the linux kernel gets compiled. It makes you appreciate all the work the devs do. I now read the title and you ask for the opposite. But someone might find these bad, so i will post it as-is
