Greenpeace & Lightship

I want to buy panorama stitching software, but can't decide between PT Gui and Autopano so downloaded both trail versions.

Nasty thing is they watermark the trail versions, so I had to work on a screendump for this blip. Sorry for the lesser quality.

Anybody have experience with either program or both? I'm open for suggestions!
