Functionality is the heart of these guides, what you are really paying for.  There are a lot of aspects I could look at with regards to functionality such as; questing path; quest progression; addon user interface; bugs; performance and many more.  All that we are concerned with are questing path (speed) & user interface.  All the other aspects aren’t worth comparing as both wow guides are light in terms of system usage, both have very few bugs, and both update your quest progress in real time.

Zygor Guides is an in-game software strategy guide for World of Warcraft. Every guide comes complete with the Guide Viewer, which displays step by step instructions of what quests to accept, how to complete objectives, when to use items, and more. Our gorgeous waypoint arrow will point you exactly where to go at all times and the model viewer will display fully rendered 3D models of NPCs and objects mentioned in the guide.
Bartender permet de personnaliser directement vos barres d'actions ainsi que les éléments de l'interface de WoW. Il est par exemple possible de rendre certains boutons plus gros voire même de déplacer des pans entiers de l'interface. L'objectif est de vous permettre de personnaliser l'interface à votre convenance, en fonction des informations dont vous avez besoin pour jouer.
