alt Hacker News"The best" for many products is often static, on the level of decades. Better e-commerce websites than Amazon will curate away all the garbage and only show you the best things. At this point you can pretty much use the top 5 results from any Amazon search to rule out things NOT to buy.
There is basically no category of anything where there is something that is THE best, once you take buyer preferences and tradeoffs like cost, quality, time, brand, etc. into account.
