Ranked in these QuestionsQuestion Ranking
Pros
Pro Easy to use
It's very intuitive and has a pacman-like syntax.
Pro Being written in Perl, trizen has an extra level of security over bash as well as performance and power benefits inherent to Perl
It is written in Perl in a functional-recurisive way, featuring full AUR dependencies support.
Being written in Perl (or any other language, except bash), it means that it can't execute/source (silently) the PKGBUILD to get information for a package, which guarantees an extra-level of security. Other benefits are the performance and power that comes with Perl.
Pro Lightweight
It's written in Perl instead of Go that makes it so lightweight.
Pro AUR comments, search and upgrade support
It can display comments for AUR packages, search for AUR packages and check for AUR package updates.
Pro Secure
The PKGBUILD is not executed before it is displayed to the user and optionally edited.
Pro Availability
It's in the Manjaro packages.
Pro AUR package names in shell completion (bash, fish, zsh)
Pro Upgrade -git, -svn and other dev packages
Pro Using systemd dynamic users if building packages as root user
Pro Show unread Arch news before sysupgrade
Pro Interactively handle common build problems (like untrusted GPG key or checksum mismatch, wrong architecture)
Pro Can install packages even when others fail
Sometimes when building multiple unrelated packages, the failure of one means that none get installed. With this helper, it will not only ask you what to do during a failure, but you can skip the package all together without having to restart.
Pro Remove make dependencies on completion
Some AUR packages require at times dozens of dependencies solely for the build process. Usually, once the build process is done, they stick around without purpose. This helper automatically removes those dependencies once all the builds are complete.
Pro Retrieve PKGBUILDs from AUR and ABS (-G/--getpkgbuild)
Pro Build local PKGBUILDs with AUR deps (-P/--pkgbuild)
Cons
Con Splits pacman -Syu to -Sy and -Su
-Sy (to refresh package list first) and -Su (to install upgrades after user confirmed the package list or has been altered it via [M]anual package selection).
