They all have different monetization strategies, and all provide good enough turn by turn directions. I regularly use Here WeGo for its offline support. Sygic is probably still fine.
I think Sygic moved to a freemium model, and I get the impression Here is subsidized by luxury car manufacturers.
Yelp crushes google maps on search.
I really don’t understand why google maps is so popular. Like search, maps is a capital intensive, commodity product with near-zero switching cost. I guess the same can be said of Coke and Pepsi, and they’re chugging along just fine. It’s a good thing I don’t work in brand management!
