My advice is get a couple months use behind you before you think about upgrading the OS. If you are happy, you may want to leave well enough alone. If you want to see what you may be missing, there is plenty of time.
If you do decide to upgrade, prepare yourself to downgrade if you have to. Also make sure you have done a backup and that you have no issues with your computer, etc. Doing an upgrade is easy enough but not risk free.
On OS 6, I cannot say for sure one way or the other that you will probably like it, or not. I did not, and went back to OS 5.
