Yeah, through whole ME3 plot we see endings of most storylines inside
trilogy. Now I'm starting to believe that all BW talk about many
different endings refered to whole ME3, not to just final moments. If
You look at this that way it really brings Your personal ending to ME
series.
But still the very ending of ME3 is plot hole (Normandy
thing) and generally doesn't provide enough insight to the fate of Shep,
his friends and so on.
It is it? Shall we abandon all hope? Now I
will be forever spoiled due to Indo Theory 'cause I believed in it, I
see all inconsistency, holes, cheap tricks, poor writeing and lazyness

We always
intended that the scale of the conflict and the underlying theme of
sacrifice would lead to a bittersweet ending
Sorry, but as following Destruction path (my ultimate goal, but it really doesn't matter) I got: whole galaxy fleet starving to death near Earth, possibly billions killed in Mass Relays explosions, dead Shep (or slightly hint that he may actually survive), those who will die on remote non self-suficient planets, whole Citadel population (with high number of refugees) killed too (assuming that they wers still alive) etc.
So I ask where is "sweet" part of the ending? That Joker, Liara and Javik who magically appeared on Normandy survived? To see Reapers destroyed? At that cost? Will their remains lying on Earth still indoctrinate like Derelicted Reaper? Come on...
So it seems that Synergy ending was really the best. Synthetics wont starve. It's great that my Shep who always encouraged evolution, development of free will etc. now forced everyone to be synthetic, stripping them of free will and choice.
He is right. I see much bitter but not so much sweet
