Quite right.  There is no point in commenting on the differences between these competitions.  Boxing is obviously a traditional competition with well-defined rules, defenses and rules for determining the winners.  It has long been an extremely popular sport.  The slap tournament I think is just commercial entertainment, very heavily advertised.  As I understand it, it takes place in the USA, where they always come up with a lot of such crap.  This is not a sport, but just a stupid show for the public's demand.  But I did not understand why in the second post of this topic there is a photo of the Russian "champion" Komatsky, because I have not heard that such tournaments were held in Russia.
