.... which is best?

Flickr. Its fluffier and has better whites.

Thanks Max ... i like fluffy!  

Seems that Flickr supports larger images, has better third party support, and will likely be around longer than pbase. The quality of the photography seems better on pbase, but the ease of use might be less. Besides, dont you want to hang with the popular kids?

I can take a photo with my mobile phone & have it on flickr within minutes :-D

pbase if your a professional photographer. Better community and more professional peer review ability there.

Flickr if your an amateur and just want a place for showing off photos

That said I just purchased Flickr Pro.
