I tested all 3 of them, and in my opinion, this one has a plus over all the others. itszdan does not create enough CC chances, watford tends to become inefficient on the medium term, that is from the 2nd season, this one hasn't disappointed me yet.
For example, with Watford tactic I got the best attack and best defense in the league for 2 years, yet each year I lost at least 6 games in the league, and drew around 7-10, which is too much.
With this one, I have the best attack and defense from the league, but I barely loose or draw, and I have a weaker team than with watford, because my rule allows me to buy only national players, so I sold for example Gabriel Jesus and instead I promoted a youngster from the youth team and trained him as a SS, improving his finishing from 9 to 15. Yet he is a good striker, but not Jesus. So on.
Last year this tactic got me 3 lost games and 2 drawn in the league. I won all the cups too, and bare in mind that the opponents have the best players in the world, all the south americans, germans, spanish, french, etc. I have almost just british talent, if you can call most of them talent lol.
Manchester United for example has Pogba, Griezman, Embolo, Rafinha, Digne, SUlle, Varane, Zaza, Morata, Laporte, Gaya, Iwobi, Martial, etc, etc, etc, yet I kick their arses with this tactic regularly, even if in terms of talent they are way better than my team.
I might be wrong, but I would definitely pick this over Watford and Dan.
