I have Kiwami and I started it today. I don't know how long it'll be until I go back because I want to finish another game before I dive in. I think its cool there is this comparison stream. I have seen quite a bit of this "Yakuza 0 is awesome, so much better than Kiwami". If it wasn't for Kiwami there wouldn't have been a 0. smh it is infuriating. Obliviously Yakuza Kiwami is not horrible. My own personal experience is playing Yakuza 2 on PS2 and then importing KENZAN!. I can't necessarily vouch for knowing a lot about this series, but I've always been interested in it. I won't be the first or the last person to say it reminds me of Shenmue, but I was on the hype train with that by owning the imported DC version.
It seems like this is a lot of work, fun work. Its awesome to see something like this. I wanted to get 0, but at the time it was more than I wanted to spend when I knew I could spend less and play the game that's apparently the first game and not the prequel. Anyway, I don't fully understand my negative feelings about this Yakuza 0> all. I'll hopefully get there someday.
