Define 'best'? So many different categories to own the title of best? Playing the odds, an app might be good in 1, or 2 areas and be mediocre in more and terrible at others too...
Sound quality, ease of use/navigation, free or pay, best in a particular genre, idle log off timetables, too many commercials, video availability, downloadable content... These are just a few categories of judgement that would be differently categorized on your priority list than say maybe mine and others. If you list say maybe 3 different categories to be best in, that would give us better parameters to abide by when making the BEST decision (lol, see what I did there in that last sentence?).
