Hylea's is a bit disappointing. While it is the right thing to do, a lot of people killed their hollowborn offsprings already. This causes a lot of grief.
Galawain's is by far the best. It's pretty much just positive. Strength and hope for the weak to get back up and move on (this includes the parents of the hollowborn as well).
Wael's is mysterious, but so is Woedica's. A restored crown and that's it. Doesn't tell you anything. What did Woedica do?
Berath's is so wrong on so many levels. Those souls belong to the living for many years and he wants them prematurely returned. It's the worst possible choice in my book.
Rymrgand: almost the same as Berath. The better part about this is that *some* of those stolen souls are damaged, but I'd still take Galawain's solution. Feeding those souls to others is probably better than disintegrating them.
