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.
I like doing achievements – and some achievements are not covered by the guide. Obviously there are lots of them. Often when you think of doing something special, it includes coordinates and places. Would it be possible to have a feature in the guide where you can plot in one or preferably a list of coordinates where you want to go, call it something, and then be allowed to run it through the awsome guide system? – the Taxi feature that directs me the fastest way to a location is fantastic. For the list of coordinates I would want two options. a) any order and b) need to be in this order.
On March 23, 2018, Zygor Guides announced that they would end support for their ESO guide. Later, via answers given on the forums, they confirmed they would not add a leveling guide for Summerset. Their guide is Public Domain with Zygor's blessing for the community to create guides. So I took it upon myself to create a Summerset guide for the ESO community.
I also wanted to note that a lot of users, I found on the Web claimed Dugi’s Guide to be faster.  However, all these users had either used Zygor Guides for very little time or had not used it at all.  I have to give a point to each Dugi’s Guide and Zygor Guides as they both deliver a great lvling speed.  For all you Dugi’s guide users out there who really feel that Dugi’s Guide is faster, I will give Dugi an extra  point.  If there really were a difference, it wouldn’t be by much.
