I agree that Aperture is not broken... it does work great with what it can do. It's what it can't do that's the problem. For example, How do you correct lens distortion? What about high-ISO noise reduction? These are just a couple of basic capabilities that a lot of photographers need that Aperture lacks. Of course, we have plugins to do these things in Aperture, but they are more time consuming and create extremely large TIFFs in the process.
I don't like Lightroom for a number of reasons, it's UI, the way it renders my 5D3 RAW files out of the box, and it's highlights and shadows sliders, which is why I won't switch to LR (although that hasn't stopped a lot of people).
Amen, brother! I find AP3.5 to be fine for my needs. Along with a few preset collections (Gavin Seim, for example), I can manipulate photos from my 5D3 or SL1 easily and get great results. That said, I do hope AP4 comes out soon with at least the features you mentioned.
