Personnally, I can't get enough of her work. Her pictures moves me deeply on many levels, most strongly on an aesthetic level. I don't give much value to an artist based on how original a style or how much social or political statements he or she tries to convey. To my eyes any good photograph of hers wins hands down up against all the Cartier-Bresson photos I've seen so far. Hers just touch me more deeply, but of course that can be just me. It's pointless to create competition in the artistic field, all is a question of personnal taste and sensitivity. I don't care who is best, all I care for is what I love and I love Vivian Maier's work. Her fascinating story is a bonus.
