It's up to your aim: do you want to reproduce others' data or do you want
more accurate simulation?
Sometimes researcher used the old and less accurate FF because they started
their simulations years ago when no new FF was born.
If you started from fresh, you should use more accurate one.
For protein simulation, you should use ff14SB.
