The only thing that Google didn't fail with was search. Stop pretending there is anything else they've made which can't be labeled as mediocre copy at best.
Please. Maps, Chrome and Gmail alone make what you said an absurdist lie. (I'll give you the benefit of the doubt and put AdSense/AdWords under "search" instead of calling them a separate product.)
Youtube and Blogger were acquisitions, but have done, y'know, pretty well under Google's roof. Android seems to be kinda successful for something that's a "mediocre copy at best".
And those are just the big products. They've had a ton of little successes too, like Earth, Docs, Sketchup, Voice...
And they've had a lot of products that look like clones (Drive, Groups). And they've had a lot of bona fide failures too.
But the point is that Google produces stuff. Facebook kinda doesn't. They improve their existing product and add features to it. Maybe that will change (c.f. Instagram), or maybe it won't. But right now I don't think you can say that Facebook has a culture of innovation in the same way that Google (or Apple, or hell, even Microsoft -- companies that ship new products regularly) does.
I am not a fan of Facebook so don't label me as such.
Google is known for its spectacular flops. The fact that they've used their cash to buy already successful services doesn't make them creative.
I view google as completely unimaginative company. Their search was nice once but right now their search results look like christmas tree so I can't admire them for that either.
