IrfanView

If you start thread comparing these two views, then the job become quiet complex to decide which the better one is. I am very use to IrfanView due to my use of this view from last few years. But when I tried a hand on XnView the experience was quiet calming. 

Excellent browser for files is the best feature available in XnView. In case of IrfanView when it comes to its available Thumbnail View, the look available is very worst.
