Different BLS futaba servos

Can anyone tell me what the difference is between these 3 servos? Speed, torque, and specs that I can see are all the same.

BLS157HV
BLS177SV S.Bus2
BLS172HV S.Bus

As I dont fly futaba radios, i dont think the S.Bus vs S.Bus2 matters, but im not familiar with the S.Bus system so I could be completely wrong

after doing some research, it seems that the 177 has a metal top part of the case. still cant tell the difference between the 157 and 172
