Alternative for putty?

The tool that I use most on my windows box is putty. I've always looked for an alternative since it lacks some features like tabbed sessions, Edit display settings such as the indent colors etc..

Poderosa (funny name :)) is an alternative which is kind off good, and has the features which is similar to Terminator in linux, the important and nice features are
1. Tabbed sessions
2. Split windows horizontally and vertically.
3. Editing display colors etc..

This software requires Microsoft .NET Framework 2.0.
