Well, as the title suggests, which is the best? As I have been reading these forums I get the impression that people are just loving the guardians, saying that an advent fleet can stay alive forever with their aid. But I really disagree. The guardians just reduce the damage by 33%. The ships they are protecting still receives 67 % of the damage and slowly but definately are destroyd. Perhaps their destruction is delayed for some time, but not that much in my opinion.
The Hoshikos on the other hand replaces the hullpoints and can thus keep the ships they are supporting alive almost indefinately. And this is the big differenc, the Iconus can not protect its fleet from getting damage, the Hoshikos can.
I have played tons of battles with the TEC (using Hoshikos) coming out of the battle with no harm to the fleet (if I also use the Dunovs) but with the Advent several ships goes down in the process.
So my conclusion: Hoshikos really outwins the Iconus, by miles.
Looking forward to any comments!
