Google maps is a mess these days. Its glitchy, slow, has broken navigation, and is overloaded with unpredictable dynamic content. It's even worse in the native android app. Id totally go for the original version but with the more recent vector maps.
Being an SPA is certainly the cause of the glitchyness and slowness as complex content dynamically loads and shifts around. It's also certainly the cause of the broken navigation, just like the original article explains.
