What about Avant Browser?

Why is it that Avant Browser always appears to be completely overlooked as an 'alternative' to that of IE, and Firefox, Mozilla, Opera and Safari, are always the 'safe options'. Don't get me wrong as a humble user I am in no way knocking any of these browsers but I would love to know what safe and ain't, and in a few sites I have read recently it always appears to be left off the list?
