well I tried most of the progs mentioned and a few more I came across. I wanted somthing that was good at viewing pics, with different options for viewing and hopefully customisable. I also wanted something that would enable tagging and searching of the pics etc.
my favourites:
PhotoManager 2008 by Proxima, very good for viewing in full screen mode you get thumnails along the top. Can add tags and assign categories too. Easy to use
Coded color pro 5.8.2
lots of viewing options, can make catalogs, assign keywords and a nice calender view.
Idimager 4.2
easy to make virtual collections and fast collections, has calender function. iptc/xmp tagging, good healthy forum
SnapAct
Free, and for viewing I thought this was the coolest. You can make Albums of collections. ITs quick at drwing thumnails. Easy to tag and then search. Can upload and sync with the web. This prog is fairly new and doesnt have as many functions yet as the others but was kind of cool.
anyway out of all the progs I tried out these are my favs.
ps If you want a simple way to edit your exif/iptc data just install the xnview shell extension
