Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Multi-platform (Linux, Windows, MacOS X)
You can use same tool in all desktop OS environments.
Pro Source code is available (true free software)
If the developer loses interest there is at least the possibility that someone else will pick up the torch.
Pro Configurable
Lots of options allow you to configure DC the way it suits you best: Tools, Fonts, Colors, Hotkeys, Mouse, Fileviews, Plugins, Layout, Toolbars, Tabs, Icons etc.
Pro Directory Hotlist
Save shortcuts to folders. Organize them in a treeview with submenus. Define a name and sorting for each entry.
Pro Powerful tcmd-like search tool (alt+F7)
Pro tcmd-like multi-rename tool (CTRL+M)
Pro DC uses TCmd plugin API
so you can use documentation from Total Commander for writing plugins. WCX (packer), WDX (content), WFX (file system), WLX (lister).
Pro Closely follows TotalCommander UX
For instance, the 'Settings | Layout' pane is quasi-identical to TCs.
Pro Very sophisticated
Although it is lightweight and simple to use, it can do very sophisticated tasks, like copying files from directories which have a certain extension or file size or have a certain text pattern in them. Also, it's very customizable and stable.
Pro It's that good, you can replace tcmd on windows too
Pro Source code written in (Object) PASCAL
It's all a matter of perspective. I'm not for an argument about IDE's, frameworks etc, but to me that's a big plus. I think it should be a tie, it's either a pro or a con or should that be neither a pro nor a con. It just depends on context.
Pro You can use Dropbox to sync
Eagle sorts files in essentially a custom folder hierarchy called an 'eaglepack'. Everything is stored locally, but you can sync to the cloud by uploading the eagle folder to the cloud.
Pro Varied import options
You can import from files on your PC or from online galleries like Pinterest, etc. On import Eagle pulls metadata like the URL the image was saved from.
Pro Fleshed out drag and drop
Thumbnails in the GUI reference the full size file in file explorer, so you can freely drag and drop into your app of choice, e.g Premiere Pro.
Pro Wide multimedia handling including image, video, gif, 3d, font, etc.
Handles 81 types of files in Windows and 90 in MacOS.
Pro Browser extensions
Has extensions in Chrome, Firefox, Safari and Edge browser. Takes screenshots of pages and lets you categorize it straight away.
Pro Can handle large files
Pro Manage and sort by tag, category, colors, etc.
Eagle includes smart folders you can configure to hide/show content dependent on custom parameters like color, tags, category, folder, etc. Eagle pulls a sample of colors from every image you upload and you can easily filter and search by color.
Pro Ideal for designers
Cons

Con Apparently only one developer
Con Freeze after mouse double-click on directory list item
Con Much slower on Linux and Mac than on Windows
Con Source code written in Pascal language
But this does not affect users negatively. It's just programmers problem.
Con Not developed anymore for Mac
Con Can't edit files on remote FTP servers
Con 30$ price
There's a 30 day no credit card required free trial.
Con Limited Cross-Functionality
There is no web version. You need to install the software if you want to access your asset from an eagle file. Missing an Android/ IOS app.
