Some SSH clients do not render mc or htop properly (or quickly) or vim is glitchy through tmux, etcetera. I have NOT encountered any issues with Bitvise.
Pro Very fast
New SSH windows pop up almost instantly when you launch one.
Pro Great option for small businesses
Bitvise is one of the few SSH clients that offers all features free for all types of users, including organizations. At the same time, there are no compromises in terms of functionality. It has an advanced GUI, corporation-wide single sign-on, learning resources including guides and FAQs, and other features.
Pro RDP over SSH
You can use Remote Desktop through SSH.
Pro Open New Terminal Console From Window
Bitvise's open new window feature is unique and very convenient, no need to enter login and password twice.
Cons
Con Hard to configure
It does not detect the installed shells (PowerShell, CMD, etc) automatically.
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.
Con Saved profiles(sessions) feature is not good
Why not have a panel to show saved profiles that the user can easily to open sessions?
Con Dropped SSH connections have to be established in new windows
The SSH connection seems to drop easier than some other SSH clients and you have to open a new SSH window to reconnect.
Con Bitvise Main SSH Client Window pops up after closing terminal window
Bitvise opens main window after closing a terminal window. If you have a dozen terminal windows opened, bitvise main window will open after closing each terminal window. It is unintuitive and annoying.
Con No SCP Support
Has SFTP but not SCP support, which is incompatible with many devices.
