A lot of things can be easily configured, e.g. color theme, size, window frame behavior, tab location, cursor style, hotkeys, etc.
Pro Integrated GitBash, Cmd, PowerShell, and WSL
Pro Is cross-platform
Even the question was "...for Windows", it's nice if you can use your tools over different platforms.
Pro Integrates with git-bash with a simple toggle in the interface
Pro Excellent interface
At start opens last session terminals. Also has terminal tabs.
Pro Color coded host
Host connections can be assigned a color, so you quickly discern them in the host list and in the connection tabs.
Pro Allows storage of login credentials
Sollar Putty creates an encrypted local file where you can store the login details for your devices.
Pro Provides significant expansion of PuTTY capabilities for free
In additional to regular PuTTY features you get multi-tab interface, auto-login, quick access to recent sessions, integration of Windows Search, and other useful features.
Con Slow with input lag
Sadly, Electron strikes again. The input lag is noticeable and annoying. Startup also takes like 2 seconds or more (On an i7 from 2016 with SSD).
Con Some functions still fail
It's huge. The amount of resources it consumes is not justifiable.
Con Cannot remove the default profiles
For example, you installed Arch Linux for Windows Subsystem for Linux some time ago, but now you have deleted it and currently use Ubuntu on WSL. After that, if you decide to try this terminal emulator, you'll find Arch there without an option to remove the profiles already included in Terminus.
Con Easy to be confused with different brands of the same or similar name
Like Terminus (Russian production company), Terminus (font) or Termius (SSH client).
Con No multi window support
Can't split tabs into multiple windows.
Con No public download
They require your personal data and a working email before you can get the program. Not a great way to spread your allegedly "free" tool.
