Pro Works elegantly in OSX
The rendering of the pages and the browser compatibility with OSX works smoothly, when compared to other browsers. Also you get very high battery life with Safari, when compared to Chrome.
Pro Extremely fast
Pro iCloud syncing
Tabs, passwords, bookmarks and, history all sync across devices.
Pro Sleek design
– No distraction stuff like favicons in tabs, all that borders, bevels and embosses in panels like in other browsers, no ugly shaped tabs.
– Neat adress bar.
– Good looking start “show all tabs” screen.
Epiphany is pretty lightweight and doesn't require much memory to start up.
Pro Fits in perfectly with the GNOME desktop
Since it is a GNOME app, you get all the benefits of the GNOME desktop. It's easy to use, Epiphany just works out of the box. It stores your web site passwords in the secure GNOME keyring, and uses your existing desktop settings to launch applications and access the network, so you don't need to configure everything twice.
Pro Excellent alternative to the most popular web browsers
Sometimes my workflow involves using separate browsers. I like mail in app tabs, but some jobs are well suited to a lighter, simpler web browser.
Pro For Linux and Windows
Available for Linux and Windows 10 with WSL, see here.
Pro Default in many GNOME versions
Epiphany has been the default browsers for many distributions that use stock GNOME for a long time now (although it's being replaced by the much more popular Firefox lately).
Con OSX only
Apple dropped Windows support after Safari 5.
Con Poor support for new web technologies
Safari usually takes its time when it comes to adopting new and useful web technologies meaning that the user gets an inferior experience compared to other modern browsers.
While Safari er is currently available gratis (without monetary charge) on Mac OS X, it is currently not libre (meaning that it does not allow users to view the source code used to create, to modify that code, or to redistribute modifications) and is therefore neither free nor open-source software.
Con Not much room for configuration
The choice for extensions is very limited, although there are decent extensions for the most useful activities and features it still cannot compare to the extensive collections that other browsers may have access to.
The number of tweaks that can be done to the browser from the options menu is also very limited since Epiphany follows a philosophy of "less is more". While this can be enjoyable for some it still hinders a lot of functionality and removes the ability to personalize the browser the way you want it to be.
