What's the best Mind Mapping Software?

I like FreeMind very much, which is a Java mindmapping tool. Colleagues of me like XMind most.

XMind has better graphics than Freemind but it's much heavier.

Pro's include:

1. Good customizable GUI.
2. Available for any major platform.
3. There's a portable version for the USB.

Con's:

1. It's java based. That makes it a bit slow.

Try using Freeplane .

Freeplane is a powerful and free software for building the mind maps. It is a redesigned version of the well known FreeMind, and is created by one of FreeMind's key developers. I prefer it over FreeMind since there are more options. Also, questions or problems with the program are answered and fixed MUCH faster.
