I think there will be an obvious distinction between both "types" of deaths.

I think the weight and shock of the snap deaths is tied in great part to the anxiety of the mystery of how they get undone.

The others received such intimate moments and we had to deal with them on a personal level. The snap deaths held a different sort of weight that yield different ramifications, and the Strange/Stark scene lays that pretty bare. Doc knew what was coming, and he knew what he was doing. The moment it becomes apparant that those deaths weren't permanent occurred when Doc told Tony this was the only way, not when the deaths actually occurred. Personally I think this is a shining example of quality storytelling that breaks those 101 rules.

To that end, the predictable inevitability of those ressurections sits perfectly well with me within the context of this story.
