Well, to me it matters more that what I did rather than how it ends in my part.
Though out of those, probably getting glassed would be fast & leave more hope for others than the Halo array option.
And it would leave less doubts about how I got into the situation, Id like to think I would be fighting the right fight.
Though Energy sword could work too, no other casualties & more personal, even leaving a chance to "return the favor" to the stabber itself.
So out of those 2, the energy sword, gives a chance for final fight & no collateral damage.
