So I completed ME3, without the Extended Cut DLC. That was....unfortunate.
*SPOILERS*
I went for the Control ending. I didn't want Destroy cause it would kill the Geth who I fought to make an intelligent lifeform all on their own and Synthesis seemed to go against everything I was fighting for throughout the series. My Shepherd fought and championed for diversity and how it makes us all stronger as a result and so doing Synthesis to remove all of that and make everyone the same was wrong to me. With Control, my Shepherd died, calls off the Reaper threat for good and everyone goes on with their lives. But then it just goes on with stuff I didn't want (like the Mass Relays being destroyed) or just left huge questions over (the Normandy, the crew etc). That ending in general is just really bizarre. To have the big bad behind the whole series revealed to you in the last 10 mins of the game, telling you which ending to pick which raises questions and leaves plotholes is just poorly done.
Having seen the Extended Cut endings, I do feel they are better and give more closure. To me, having seen them all, my ending would be the Refusal ending. Yeh we would all die, but fuck it, we would die on our terms, knowing that in the end we died free because it's what we had all fought for all along. I just wish the actual ending for that was better, maybe showing people I know fight until the end, the Normany blowing up or something, rather than just a Liara voiceover. If you follow the Indoctrination theory though it looks like the Destroy ending is the best ending of all.
I'll write up a review at some point but yeh I wasn't really into ME3 in general. It did some things right, like the Genophage arc, but a lot of things just lazily written like the Rachni stuff. To me, the whole of ME3 is the ending to that series, not the last 15 mins. I enjoyed the series, would still recommend it to anyone, but I was disappointed in the end product. You could sense that the short development time affected the game, it was glitchy, buggy, fetch quests aplenty rather than genuinely interesting side missions, fewer dialogue options and what I consider to be a, mostly, lackluster conclusion with or without the extended DLC. At the end of the day, it is an ending to a video game, it's no big deal I applaud the series for what it has achieved and will look forward to the next installment and where it takes the series.
I still think Fallout 3's ending is worse.
