I've been playing a lot with both HE and HEAT and I have finally decided to stick to HE. It seems like HEAT doesnt do as much spalsh damage but its not gamebreaking. You can still get a lot of kills with it, the only difference is that yuo'd have to aim a little better. My top scrore was 35kills while camping the enemy Sundy at Broken Arch. It did take a while for me to kill it because they kept on repairing it but in the end I only had 4 shells left the rest didnt fit on one screen
