"Abandonware" is ex-Bibble-now-Corel-Aftershot-Pro. If you're lucky they might release twice a year without a peep otherwise. I totally expect that tool to go away, which is too bad since it has had great promise on the RAW processor front. Just extremely poor execution by the previous and current owners.
You may not care for the kinds of updates you currently get on Aperture, but it does get them and can hardly be called abandoned. And you can produce stellar images with the tool. I am proficient in and have both LR and Aperture and greatly prefer the Aperture workflow and UI (I find LR's UI to be atrocious). So a lot of it is certainly personal taste and what you value. Yeah, it'd be nice to see on-board lens correction, etc but it's far from being a showstopper for everyone. So bottom line, what works for you...works for you. You might feel it your life's mission to convert everyone to the "Lightroom Camp" but in the end, all of these are just tools and the image is what matters.
