i don't like how you can be killed while in VATS
FO3 was better with the VATS
It was also unbalanced.
In Fallout 3, you could get hit by missiles, fire from multiple enemies and be beaten with baseballs bats while in VATS and unless you started off with barely any health, you would walk away from it. In fact, by pulling back after each VATS attack and waiting for AP points to refresh, then VATSing again, you could be almost invincible.
In fact, with Grim Reapers Sprint, you could VATS almost constantly.
Now, you have to consider the situation before using VATS AND you're not going to be relying on it constantly.
