4-4-2 or 4-3-3 next season?

Last summer we played the entire pre-season in a 4-4-2. We then started the season in the 4-4-2, but quickly reverted to 4-3-3. (Admittedly we lost Benteke to injury very early on.) We finished the season strongly in a 4-4-2 with notable highlights being the Arsenal away game (4-4-2) and Bournemouth at home (4-4-2) where we scored FIVE goals at home - our previous best in the other 18 games was two goals. I can also remember many games where we started 4-3-3 and won the points after switching to 4-4-2 late on leading to a massive improvement.

What are people's thoughts on what formation we should play next season under Hodgson?
