Re: “best vs better”: claiming that something is the best can be a weaker claim than claiming that it it better than something else. Specifically, if two things are of equal quality (and not surpassed) then both are the best, but neither is better than the other.
Apocryphally, I’ve heard that certain types of goods are regarded by regulatory agencies as being of uniform quality, such that there’s not considered to be an objective basis for claiming that your brand is better than another. However, you can freely claim that yours is the best, as there is similarly no objective basis on which to prove that your product is inferior to another (as would be needed to show that it is not the best).
