ACDsee is better than IrfanView IMHO because IrfanView has the worst icon(s) ever. I think if IrfanView changed his icon, his product would be better. Honestly, A red splot does not inspire me. ACDsee’s icons with the file extension written in the icon make so much more sense. Only problem is ACDsee isn’t free. Oh, and ACDsee has lots of cool editing features too… If I was to buy it, I’d buy the powerpack.
