It's not the individual items on TomTom's menus that are confusing, it's he ease os recursion and being presented with essentially the same menu multiple times and then having to back out of them. Even something like the Demo of your route was infuriating because it just kept looping but didn't indicate that it was, nor did they provide a way to turn it off without again going through a bunch of clicks through the menus. There's definitely a lot more clicking involved in TomTom's app.

The Edit thing is an iOS quirk. Edit is used in a lot of apps simply to allow deletion of list items, not necessarily to add more - the add button is usually available independently of the edit. I haven't tried creating a favorite yet, but I'd assume that you do it while looking at a location and not by clicking on the favorite button in the tab bar - those buttons usually take you to lists of things, they're not function buttons. Those will usually be at the top in an iOS-style app. For better or worse of course, because IMO, Apple's apps are not the end-all and be-all of design. Quite frankly some of the default-style iOS app design is just awful. iPod app for instance.
