The 180 that always passes through is going to be more consistent. I've had bullets that did not pass clear through show more variability in results. Sometimes they were friggin' spectacular, other times the seemed to have no effect for a while.
Personally, I prefer reliability, short tracking, rather than a mix of bang flop and longer tracking or even lost game.
The ol' "absorbing all the energy" schtick was nonsense when I first heard it in about 1968 and it hasn't gained any ground. ALL only matters if you barely have enough. If you use something a bit more appropriate for the job, you'll have enough. Having enough is important, having all can still produce a failure.
