In my opinion, it's an apples and oranges situation that entirely comes down to personal preference. Godzilla Minus One, The OG Godzilla movie and the like are trying to do VERY different things with the character than are most Showa era movies or the Monsterverse movies and I honestly think it's important that both continue to do what they excel at as they're both good in their own ways. You obviously can't have Godzilla as the villain embodiment of nuclear destruction in every single film because it's just gonna get old after a while, no matter how good the writing it. Having those movies running in Japan, while the American Monsterverse movies highlight the cheesier elements of Godzilla and focus more on the monsters as characters in their own right while beating the shit out of each other, puts the franchise in as good a position as it can be because it gives the fans the choice. Now me I'm a lifelong Power Rangers fan so I personally am gonna stick with the Monsterverse...
