I concur on "really good" but have to disagree on the "series" part. Children of Time is a remarkable book, one of the best science fiction stories in a very long time.
Children of Ruin is ... okay. Children of Memory is not a good book, IMO. Both of these suffer from the same mysticism-used-to-spin-up-a-red-reset-button plot device plague that fundamentally guts Xenocide. Nowhere as bad as that, of course, but the unpleasant echoes are there.
As it happens I'm in the middle of the Architects series and while it has its distant whiff of Stainless Steel Rat[ß], on the whole the series and its universe have so far remained consistent.
ß: Stainless Steel Rat was notorious for repeatedly putting the protagonist into impossible situations and then whipping up near-magical pieces of technomancy that just happened to solve the problem of the moment.
For me, Children of Ruin had more of a horror focus to it and left me with much more icky feelings than the brilliant positivity I felt at the end of the first book. It was still well done, though.
I agree that Children of Memory is not very good, mostly because it repeats itself so much. That could've been handled differently while still advancing the plot. I LOVE the overall concept, and the author's skills describing Gothi and Gethli's unique kind of intelligence was great, so I was okay with it overall... but too much of it was just a slog. First book is by far the best in my opinion as well.
I always took the Deus Ex Machina in Harrison's books to be just more of the satire. He never really takes his settings or characters lightly, but the presentation is almost always aimed at comedic effect.
