The answer may be in your intended use of the program. If you are a professional, running a cottage industry model, stand-alone portrait studio or commercial photography business, then something like Lightroom or Capture One is a virtual necessity.
If you are an enthusiast who wishes to catalog all your photos and perhaps do some efficient post-processing, Photos will probably fit the bill nicely.
Apple's game is all about having the best consumer interfaces to whatever devices and applications they sell. Photos looks like it will deliver a very smooth, intuitive, and fast user experience.
While it might not have ALL the bells and whistles that Aperture does, Photos will be more efficient to use, and it will sync seamlessly with Photos on the iPhone and iPad and iPod Touch. If you are heavily invested in the Apple ecosystem, that may be enough to tip the scales, right there.
Years ago, when Aperture and Lightroom were both at version 2.x, I took a four hour course on each of them at the DIMA Conference (Digital Imaging Marketing Association an arm of the Photo Marketing Association International). It was apparent even then that Lightroom would win the mindshare of the professional crowd, because Adobe was listening VERY carefully to the most influential pros in the industry, whether at PMAI's conventions, or PPA's conventions, or WPPI's conventions. It was also developing a cross-platform application. Apple would have done well to follow their FileMaker Pro database model, and do cross-platform development as well, but they kept Aperture a Mac-only app.
Lightroom has evolved nicely, and is a de facto standard of the independent professional photographer. It does, in software, what custom lab technicians used to do in a darkroom and much, much more. Combine it with Photoshop for pixel editing (retouching, masking, layering, compositing, color separating, adding text...), and you have a graphic arts tour de force. Add plug-ins for retouching automation and sharpening and other effects, and you can do virtually anything in the photo world.
The downside of being able to do anything is that there is a huge learning curve to doing anything. Adobe has been selling Photoshop for 25 years, and Aperture for about a decade. Both apps can seem like bloatware to a new user just getting into the field of photography, or to a user who has skipped a few upgrades and just switched to the new versions. There are now so many menus, submenus, palettes, and settings dialogs that it is VERY easy to get lost, dazed, or at least confused.
Apple evolved Aperture to a point where they saw their market shift away from the professional crowd and toward the digital enthusiast. They primarily serve the mass market, not the pro market. Their interfaces are built for speed, efficiency, intuitive understanding, and tight integration with other applications and devices. If that's what you need, go for it! Keep using Aperture until it's orphaned abandonware, and/or upgrade to Photos.
If you're a pro or pro wannabe, you're probably wise to look at Lightroom and Capture One. But install what came with your camera, and look for updaters on the camera manufacturer's web site. There may be times when you need it.
If you're an enthusiast, you have to decide on a level of software that matches your level of enthusiasm. Be honest with yourself Do you want to "fall into" your computer, or do you want to have a life outside of your hobby?
It's like learning whether you want the discipline of exposing JPEGs correctly, with the correct camera menu settings, or whether you just want to get the exposure "close" at the camera, and spend lots of time fixing everything in a raw editor.
If your needs are highly creative, you'll probably shoot raw and spend many satisfying hours at the computer. If your needs are to have fun making nice images to share with friends and family, then you probably use your iPhone and a mirror-less camera on Intelligent Auto, record JPEGs, and tweak them slightly.
While Photos will be a raw editor, the range of tools will be limited when compared with Lightroom, Capture One, or Aperture. If you're an enthusiast with a life outside photography, you will APPRECIATE that. If you're a working pro, that will probably frustrate you.
