Facts:
High pressing increases your defensive efforts. It is always more effective to play with it than without, but 30-35% more condition will go to waste, so be careful and don't tire your players up before the match is ended. Sometimes man-to-man is more effective than high pressing, sometimes otherwise; both increase the condition loss.

Opinion:
I use HighPress or m2m separately only in important and difficult games; together only in the last half of those games if I really need it. None of them in easy games (less condition means less training, means less team quality).
All the ND-style formations can be quite effective in certain situation, but on the other hand they can be easily countered. These are pretty straightforward and not flexible formations.
4-3-3 has only three midfielders, and this is another weak spot of this formation. There is a common opinion that AMC/L/R+ST are usually more effective than a tight pack of strikers.
