They used to be but iirc SI put a lot of work into improving the default tactics for 07.
It seems to work best for me when my normal tactics start to get stale (team reranked, tactics sussed whatever) and invariably if I choose the normal 442 I win the next game as it seems to reboot my team.
Although
imo it shows how unrealistic the game can be as it shows how you sometimes just have to arbitarily chance your tactic to get going again as tactics are much more important that the personel you have- which
imo is wrong, especially with the evidence of people like Cleon winning the EPL with Sheff Utd (?) in their first season etc.
