What's the diff between this two related to a camera's abilitty to take pics?
If I want to upgrade my cam does it make an important factor?
Thanks!
PS I am considering FZ-20 and Oly 5060.

I know someone selling an Oly 5060 for a good price but it's in Switzerland (CHF 400)

RAW is the shot as the sensor sees it - unadjusted by any processing in-camera - and allows an extensive level of (DPC legal) tweaking after taking the shot. It's almost like shooting, then adjusting everything for the shot (white balance, temperature, hue, exposure) on the computer.
I love it. Tiff is just a different, less wasteful form of compression.
If you don't mind a bit of computer work then go for RAW. You can always switch to JPEG mode for 'quickies'.

Tiff is better than JPG because it can be edited without loss of information (no image degradation). The downside is that TIFF files are typically HUGE and will chew through flash card and disk space aggressively.
RAW also allows you to edit and resave without image degradation, however there is no post processing. So, a RAW file will need levels adjustment and sharpening while a TIFF file will come out ready to go. This is good if you don't like post processing, but bad in that the camera makes best guesses about sharpening vs noise, white balance, etc.
In general, you have the potential to achieve better quality images on a system that shoots RAW vs one that only supports TIFF (or JPG). Whether or not you reach that potential is up to your post processing skills. In many cases and averag ephotographer can get better quality form JPG because the camera's heuristics exceed the photog's editing skills.
My adive is to look for a camera that supports RAW so you have something to grow into. TIFF, in practice, does not seem to me to be a good format for capturing images.

What I like is a camera that can take a raw photo but at the same time save it as a jpg. This makes browsing the photos much easier since jpgs in general load much faster then raw file. Then if you find a photo that you want to make as good as possible you can load the raw.
The F828 always saves a jpg when it take a raw photo, the Canon 20D can be set up to save a jpeg at the same time or you can just get the raw or just the jpg.

This is all funny stuff cause my 1Ds saves files in raw as tif. files. You still can make all the ajustments just like a CRW. but when you check to see file type before any alteration it shows up as a tif. - One f.

"TIFF" is the file name (Tagged Image Format File) and ".tif" is the 3-letter standard file extension tag. Ditto JPEG vs .jpg....

It's not exactly a TIFF file... That's just the operating system's best guess at how to interpret it. Linux does the same thing. A TIFF file is really more of a standard for how to enclose data than it is a standard for how the payload looks. So, in most cases a RAW file is funky cargo in a standardized container.
Since there is a real paylod format which is considered TIFF, I tweak my operating system's settings to show NEF (substitue CRW for Canon folks) as "Nikon NEF" rather than TIFF. Doesn't change functionality, but I made a cool bright Nikon icon and I like seeing it to differentiate the raw files from the JPGs more clearly in a packed directory.
