Pro Flexibility in platform support
Originally developed for OS/2 (as Zap-O-Comm), Zoc is currently available for Windows and Macintosh.

Offers a thumbnail view of all session in thumbnails and type commands to all sessions at the same time.
Pro Supports serial and dial-up connections
In addition to telnet, ssh, and rlogin, ZOC supports direct serial connections, modem dialing, and named pipes.
Pro Tabbed sessions allows for easy navigation
Tabbed sessions mean that multiple items can be contained within a single window and can be easily navigated by the user.

Zoc allows for every UI component except the title bar to be hidden. All features are accessible through the context menu.
Pro Auto-Highlight feature
Feature to search for text bits in the data stream and highlight them with color/background.
Con Can not save passwords
Anyway, you can use "PuTTYgen" to generate a key pair, then use "Pageant" to do a password-less SSH remote login.
Con Ugly design, too simple
Looks very dated. Does the basic functions very well, but not much more.
Con Lacks features
It is JUST an SSH client. There are many other options with built in X-servers, Multitabbing, etc.
Con only one session
cannot open a second session in the same window
Con Tedious logging/tracing
Its tedious to set up logging and tracing (e.g. for serial connections).
Con No global settings
If you want to change a setting for all your connections, you'd have to do it individually.
Con No login scripting
Con Options creep
It has so many options that it's hard to find the one you need.
Con Not free
Zoc requires a commercial license in order to use it, implying that it's not free.
