Alternative to PuTTy

I've used PuTTY as SSH telnet client in windows for couple of years. It has been doing a great job so far, but now I do want a better one. At least, a new one could provide multiple tabs.

I find an alternative Poderosa.

Its look is quite nice, simple and now I can telnet with multiple tab session. One downside it trades is more configurations have to be done before you open a connection. And thus a bit slower in creating session.
