I found the ending slides just weren't that different for...any of the endings. Just "warneverchanges world I found not the one I remembered warneverchanges moving on warneverchangeswarneverchangesBeetlejuice".

I actually had a much longer post written that I deleted because, in the end, there's not that much to go on from the game. Conversations with the faction people are kind of vague because you get very few opportunities to ask many questions and they kind of assume you get their general gist from the start. Interactions with them are pretty minimal and there's so much game-logic in them that they border on slapstick. (Sniping a scribe you're supposed to escort gets you quest completion XP?)

Mostly, people seem to project stuff onto the factions. (The Minutemen are the most understandable example, and it's unsurprising that they seem to come up frequently in people's ending justifications.)

It's actually kind of annoying. I could write something to justify the Brotherhood as anything from fascist (which I don't buy) to feudal (which is almost certainly their target) without ever really contradicting any of the in-game material.

I can say that the Railroad is concerned with humans but prioritizes synths because other people are helping humans, but I can also say that they just don't really give a shit about humans. (A few members say the former, but they ignore really easy opportunities to improve the lives of humans as well.)

I dunno. I miss the ending slides from Fallout 1/2/NV, which would really have helped to clarify wtf happens after the final kerfluffles. (Not that they would have worked as well with so few side quests and communities.)
