Best compression method in Photoshop CS3

[Layne.]

I use photoshop and it gives quite a few Compression methods for JPEG images for example

Progressive  (Scans 3, 4 or 5)
Baseline Optimized
Baseline "standard"

So which one is the best to use?

I think it is obvious that progressive is the best. I have not used any because I don't have CS3 though.

I have CS3  and it dpends on the photo.  No one is best.

I have Photoshop Elements, and I just use the 'save for web' function. I loose no quality, and the photo is almost always under the limits.
