What I like most about it is that when it’s running like it should it is simply stunning when flying over certain places. Like yesterday I traveled all around the Portuguese island of Madeira. Pulled up Google Earth on my second monitor and found some breathtaking scenery and with the POI’s from Google Earth you can gain a wealth of knowledge through use of the internet and really enjoy the experience for both the beauty aspect as well as an educational experience. 
What I like least about it is that when it’s not running like it should. Then there is nothing at all to enjoy and none of the above applies.
