Pros
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 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 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.
Pro Extensible Kitten framework
Supports plugins to add features one at a time for those who need them. Examples include Unicode input and side-by-side diffs.
Pro Window tiling
Very elegant keyboard shortcuts for creating and navigating between tiled terminals within each tab with no appreciable lag.
Pro Tabs for multiple instances
Operate several terminals from one window using the tabs feature, allowing you to make simultaneous connections to different remote hosts.
Pro Controlled and configured from the shell prompt within the program itself
No graphical menus to clutter the screen saves system resources and time once you learn that all those options are still available from the command line within the app.
Pro Scrollback buffer viewer
Allows for viewing the scrollback buffer in an external pager of your choice ('less' by default, with support for 'more' and 'most'), a huge benefit for turning actions taken in a live terminal session into a script for efficiency or dissemination or collaborating on workflows.
