The best one is the one you most like to use buts its got to do what your clients want.
I don't see how the client's wishes have anything to do with it as the graphics produced on all the packages are available in all the standard file formats: TIFF, JPG, GIF, PNG etc, etc. It is true that each package has its native format for files that are wip, (
photoshop and elements use PSD, Paint Shop Pro uses PSP - don't know if that's true now that Corel owns PSP program) but you'd never supply a graphic back to a client in a native file format 'coz they are unlikely to have the original software to view it.
I've used quite a few packages (in Windows and Mac - but prefer Windows) over the years and before Corel took over Paintshop Pro, I was an avid supporter of this package. The user interface is now far more complicated that is was in say, Version 7 (still available if you want it) to the point that simple tasks appear more complex to carry out now.
Photoshop, and its lighter version, Elements, are very good packages and every bit as intuitive to use. Elements lacks a masking function - which can be a pain - but there are some things you can do to overcome this. It also lacks the ability to work with CMYK/RGB channels which you cannot overcome. The price difference for these functions is dramatic however, so if all you are doing is resizing pix and tarting them up for web graphics go for the cheaper option.
There are other programs around for doing this work however, and they are free. The GIMP (the GNU Image Manipulation Program)
www.gimp.org/ is an open source graphics programme that appears very powerful (albeit confusing to move to from PSP or PS) and does everything that Elements does at least, but I haven't tested it extensively, so it may even do everythig that Photoshop CS does.
The other very powerful program that's free to use is
www.irfanview.com/ that provides batch processing on images so you can resize, rename, shove images into new directories, sharpen images on the way through (and has other filters too), convert from one file format to another and a whole bunch of other stuff to make image conversions on multiple images much easier/faster. It even has a passable slideshow function built in.
