In the movieverse, Sentinel's rust cannon is far more deadly than Megatron's fusion cannons
Megatron shot once at Optimus in TF1. All it did was knock him back a hundred feet, no actual damage.
He did kill Optimus with it in RotF, but that was after slicing into his spark, just shooting wouldn't have killed Prime. He also mortally hit Sam with it, but Sam's a puny fleshling.
He critically wounded Sentinel with it in DotM, but it still took Prime a headshot and a torso hit from point blank to put Sentinel down.
Sentinel's weapon on the other hand was only shot twice in the film and the toughest Autobot of all died as a result. If you take the deleted Twins scene into account, he made three fatal shots and a fourth in Ironhide just to be sure. That's far more deadly with less effort.
