Playstyles, just a big fake?

Was always sceptical on what difference playstyles actually make and now with EAs bakery it becomes clear that the impact is none or little. Have used the bakery for 5-6 players and honestlty feel almost no difference in players gameplay from default without playstyles and after 2 playstyles+ and 8 playstyles has been added. The players feels almost identical and no or minimal boost with all those playstyles added. Played 4-5 games with the default players and have now played about 10 games with playstyles added. Any other comments on this?
