Besides, when you preserve the base, it remains completely intact as you can see in the actual Mass Effect 2 ending, while in Invasion the base is obviously destroyed with only that chunk of the base still remaining intact. I'm quite sure that same chunk is also shown during your conversation with the Illusive Man on Mars early in Mass Effect 3, but I will have to play it again to be sure. I rest my point that Paragon is the canon way.
