What I have not seen anywhere, but would like to see, is a comparative analysis of the players available on iOS. Without this, asking what the "best" is is a fruitless endeavor which just gets folks mentioning what they use or like best and then it comes down to answer by popular vote, which is no answer at all. I have several players on my iPad (which is one reason I have 300+ apps on it) but I still have no clue which is best. Having many means if one doesn't have a feature I need at the moment, or if one player doesn't work on a particular file, then I have several other options to address the matter.
