The 4-4-1-1, if you have the players to play with a 5 man midfield then i suggest you do so it works really well with the amc helping the midfield. This formation works really well against the big teams and makes sure they don't dominate you as much, the amc plays a role like Wayne Rooney does with Manchester United.
The 4-3-3 with wide midfielders, I use this formation when playing lower rep teams or I change to this formation when chasing a game. Works very well if the other team aren't playing 5 in midfield if they are you will just get dominated.
