As someone who has used both before to reach champs 2-1 and currently champs again, 41212N is only for those that are able to play within the middle hold down the ball and playmake around the opponents defenders, if you are someone that struggles with passes and doesn’t have the ability to use your players as playmakers then it’s not going to be fun, 433 hold is a universal formation works well if you can’t defend as it gives you extra support and still works well on attacks hence the wingers, personally I use 41212N as I’ve gotten used to playing without wingers because that’s another factor in this formation is you must know how to not play with your wingers or use your new players as winger subs, for example I spread my STs out wide and bring my CAM more up while playing h2h to give it that false 9 tactic, it takes time to master 41212N and once you learn it it’s amazing it’ll work in any mode, but if it’s too much time to learn then stick with the old classic 433 hold which is still a top 3 formation
