Best? Oh my.
The problem with the question is that there is no single question in it.
There are case fans and cooler fans. There are fans of various sizes. There are fans of various colours and led lights. Some are more louf than others, but even a loud sound of one model can be nicer to listen to than a horrid tone of a more silent model. And even with the bearings, many have specific advantages, usually marketed by their maker.
And finally, the "very best" tends to be the one that is not in stock in any store.
I've seen names. Scythe, Thermalright, Yate Loon, San Ace, Noiseblocker. Not sure if I remember those right for all but one I've never seen in real life. IIRC, 'Martin' is the name of a user that has posted several good benchmarks about fans on various websites.
