Poch changed his formations constantly, tactically he'd change loads and loads of stuff in-game (go 4-4-2/4-2-3-1/4-14-1/3-5-2-2, whatever) sometimes it paid off others it didn't. But between the two scenarios, I'd rather be the team on the ball and struggle to break down the oppo camped on the edge of their box than be the team without the ball struggling to get out of our own half.
Cor if we could get away with playing 3522 every week we'd win the world cup!!!
