I am pretty much a newbie at photo restoration. I bought PaintShop Pro Ultimate X2 some months ago, but just started really working on it a month ago or so. Then by chance I got a free Photoshop Elements 6 when I purchased a wacom graphite tablet.
Now that I have both I can compare them.

What I like about PaintShop Pro is that it is so easy to size the brushes and the zoom tool. I am having difficulty with that on Photoshop Elements. And the zoom in Photoshop is driving me crazy.

Another thing that I like about PaintShop is the Scratch Remover. :DAs far as I can tell there is nothing like that in Photoshop Elements.
Everything for me so far has been trial and error. I have colored serveral BW images in PaintShop Pro, but have yet to complete one in Elements. I am not satisfied with my work yet.

I have a lot to learn.
I find Paint Shop Pro X2 easier to work with, but then that could be just because I have become more familiar with it.
The on screen menu on PaintShop Pro Ultimate X2 is also easier to work with and find than the one in Photoshop Elements 6.
