I've been using ConEmu just for the tabs. You can even have Powershell open in some tabs and PuTTY open in others (although that's a bit of a pain to set up).

I've been using ConEmu just for the tabs. You can even have Powershell open in some tabs and PuTTY open in others (although that's a bit of a pain to set up). I really don't like the default ConEmu configuration, but it's flexible enough that you can make it do just about anything if you poke at it enough.
