I recently switched from about 20 years of Putty use (some years more than others, I ran Linux on the desktop for a long time) to Windows Terminal and the windows included openssh. There are pros and cons. The new windows terminal is very nice but there's still a few annoyances. Having an actual ssh config and almost all the capabilities (no ControlMaster/ControlPath because no files as sockets) is very nice.
I probably would have been fine staying with Putty though if pageant hadn't started having reliable (but weird) problems when handling more than a few auths from remote in a short period, making Ansible unusable when running from my work VM with agent forwarding.

Some screenshots to get the idea of its ui: https://www.google.com/search?q=winsshterm&tbm=isch
ssh [letter][tab] gets me a list with my Zsh config. I looked briefly one time and couldn't find what I was looking for.
I have a fairly large SSH config file, and needing to open it to copy and paste hostnames from the file is the main reason I just use WSL.
It actually works on unix, which is usually uninteresting but I used it once when I needed a serial console client and wanted a friendly GUI. So it can* be useful:)
There was some sort of v4 -> v5 open-source -> commercial switch.
Commercial version: http://www.poderosa-terminal.com/
OSS version homepage: http://poderosa.sourceforge.net/
Source (last change in 2019): https://github.com/poderosaproject/poderosa
Releases (last release also 2019): https://sourceforge.net/projects/poderosa/files/releases/4.4... (also on GitHub too, switch to the "tags" tab)
Seems to be .NET based, and relatively simple in terms of available functionality and featureset.
After spending hours looking for solutions that were purpose built for this kind of thing I gave up took PuTTYs source and made some tweaks to the UI.
The source was so easy to work with and I was so grateful that the license allowed me to do this.
The custom client only ran for a couple of years because the web replaced green screens. And being a *nix guy I don’t get much need for PuTTY in my day to day. But I’ll always be grateful for PuTTY for making that particular job possible (and secure).
