Pros
Pro Official Android app
If you have need to manage or organize, share or export your bookmarks on the go, Atavi offers an Android app which provides a quick and easy means to do so. The web page interface on mobile is fine for visiting your bookmarks, but the app brings the smooth drag-and-drop and long press inputs that are needed to easily rearrange or share your collection.
Pro Search engine integration
At the top of your Atavi bookmarks page on each browser tab is a search field, which can be set to pass your query to Google, Bing, Yahoo!, or Yandex. There's no need to lose the familiar new tab page search field when switching to keeping your bookmarks with Atavi.
Pro Unique implementation as a browser homepage
Atavi is able to be used in almost any web browser and platform because it bypasses the native bookmark management, instead providing access to your links through a responsive web page. With every new tab opened, your bookmarks appear with all the grouping and sorting options you expect from the native bookmark manager.
Pro Full five-browser support
Atavi is developed to render properly on both the desktop and mobile versions of Internet Explorer, Firefox, Chrome, Opera, and Safari.
Pro Stable browser extensions for Firefox, Chrome, and Opera
Atavi's browser extensions further simplify use of the service by ensuring that new tabs display your Atavi bookmarks and providing a one-click mechanism for importing bookmarks you already have in that browser into your Atavi account.
Pro Multiple layouts to choose from
Three possible layouts are available on-the-fly for your bookmarks page: traditional speed dial boxes, multi-column list, and a detail view with one bookmark per row which displays the URL as well.

Cons
Con No support for multi-level folders structure
Atavi.com does not support a multi-level folders structure. When importing such structures, all sub-folders will be placed at one level. Folders with the same name will be merged into one.
Con No iOS support
It doesn't support anymore iOS.
Con Does not sync passwords
If youre afraid due to the lack of password syncing with xbrowser, this problem is easily fixable by using myki password manager. It supports all major operating systems with secure features that work alongside xbrowsersync perfectly. myki is available as a chrome extension, and for android, iphone, mac, windows, and more!
Con Doesn't support new Firefox for Android
Maybe not the developer's fault but since using Firefox as main browser, the cross platform niche can't be satisfied. Will be looking to jump ship once the extension is added to the very limited pool Firefox Android currently has.
