Con Not for daily use
Tails is a privacy focused Linux distro. The updates that you will receive are only for improving privacy and not for improving user experience.
Con Saved states are not present for security
For security reasons, saved states are not supported in Tails. Files can be stored in a separate, persistent volume which must be accessed with a root password. Personal settings (e.g. -- keyboard layout, window settings, etc.) are not saved persistently across reboots. This can be a hindrance for anyone not using English as their language, or not using a QWERTY keyboard layout.
Con You can't install it to a hard drive
Con Slow internet
Tails uses the TOR network and as a result the internet on your computer will be very slow.
Con Only GNOME desktop environment

Since Parabola is a completely free distro, there is no non-free software available and the community repositories are small compared to the AUR.
Con Won't work out-of-the-box on the most PC's
Almost all PCs need non-free drivers but Parabola has none to offer.
Con Incompetent developers
They only care about removing non-free software, rather than making a properly working OS.
Con Serves no purpose
It's just Arch without non-free software and is basically a niche OS with few users.
Con Same cons that apply to Arch Linux
Con Not compatible with AUR
Unlike other Arch-based distros, this free distro doesn't support AUR.
Con Not really free
People have to pay hundreds to maintain this distro.
