There is no one reliable distro. Mint, itself is based off Ubuntu and also releases LMDE (Linux Mint Debian Edition).
If reliablility is measured in terms of how stable a distro is, then likely Debian with it’s conservative approach to packaging updates comes to mind (No wonder large number of distros are based off Debian only).
I would even argue as long as someone isn’t messing with a niche distro such as KDE Neon( meant to showcase KDE packages) or Linuxfx (or whatever it has renamed itself to, one of the few shady ones IMO ) or Trisquel OS (a GNU certified distro where running into dependency hell isn’t new); it will suit user’s case.
Debian, Slackware, Void, Zorin, even rolling release like Arch (basically any one that meets the user’s use case is reliable)
