Pros
Pro PAC is pretty simple and does its job of collecting and managing a list of connections that can be quicly used to connect to some machine through SSH
Pro The Reference SSH Client
If you find samples or tutorials about SSH, they almost always refer to OpenSSH. It bascially defines what SSH is.
Pro One of the most trustworthy development teams on the web
The development team of OpenSSH is part of the OpenBSD ecosystem. Their implementation is basically today's technical reference for any SSH client.
Pro Available on virtually any platform
MacOS. Windows. Core component on any Linux flavor.
Pro Standard implementation that documentation for all other tools assumes you have installed already
A lot of other tools (e.g. git) are based on this for file transfer.
Cons
Con The developer officially abandoned the project
Early in 2017 the developer announced that he had no interest in continuing to develop it. Not a single line of code has been added or improved since then,
Con Heavily dependent on long-forgotten libraries
PAC Manager draws its underlying terminal functions from the Perl libraries written to interface with GNOME Terminal, circa...2006. The libraries have been untouched for at least five or six years, and just recently have begun to be removed from major distribution repositories like Debian and Ubuntu. It's a chore to get them installed and will only continue to get harder.
Con The tool has problems with blocking focus on its window, so sometimes it's hard to quickly switch to another one
Con No host list
Has no functions to manage huge numbers of hosts.
Con No way to organize SSH connections
No way to organize SSH connections.
Con Command line tool
It can be difficult to use from a command line interface.
