I think it might be, but it'd be good to get your opinion.

I think it is 64% likely to be true.

Support your opinion with some facts, research?

42 is the obvious answer to THE question.

Nope, 17 is the best! :)

64 is a very great number. But I think each number has its own right to being a great number. 64 is pretty great because it has a nice solid roundness to it, that comes from being a power of two, namely, 2^6. It's the first nontrivial sixth power which is pretty grand, but have you tried dividing it by any other number? It's not so pretty. So, from a division perspective instead of a strictly multiplicative perspective, it's left wanting. What's the best type of divisorial number? Something that gives you a great wealth of divisors, possibly.

Mathematicians devised a metric for what numbers are the best divisorially, say perfect numbers. Those numbers whose positive divisors aside from itself sum to the number itself. Like 6 (3+2+1) and 28 (14+7+4+2+1). So these are the best in division. It all depends on what you ask from your numbers to be the best. Also, which are the most interesting prime numbers of 2? A Mathematician may say ones where 2^n-1 is a prime number. A so-called Marsenne prime. It's unclear if there are infinitely many, an unsolved problem in mathematics, but if you look at 64, well, 63 is not prime, nor is 2^64-1. So who knows if you can really think of 64 is the best power of 2 even. Just depends on your metric. But nonetheless it's a pretty awesome number.
