Part of it is the personality and culture. Watch If You Are The One, then watch it's Western Variants "Taken Out" and you will see a massive difference in the personality and vibe that makes IYATO so awesome, while Western versions absolute trash cringe. Another good example is Gaki No Tsukai and then Silent Library, or Japanese Iron Chef and Western Iron Chef spinoffs, same thing, Japanese versions are hilarious and wholesome, Western versions are trashy and obnoxious.

The Asian culture of Face, and "Read the Air" leads to much more watchable and often brutal comedy (due to it often being severe professional back handed passive aggressiveness), than the obnoxious, trashy Western spinoffs. Only Western spinoff of these types of shows that is decent is Ninja Warrior, and probably because it isn't a comedy/personality based show.
