You may be interested in MobaXterm. Don't let the name fool you; it's a good SSH client for Windows. I spent 20 years or so hassling with PuTTY, and just discovered this a few months ago. More people should know about it. I still need pagent for git, and the like, but at least Moba solves the set-the-terminal-options-once-for-all-SSH-sessions problem.
