I don't think I've ever had an issue with Apple Maps interface. It's fairly gorgeous. It's the actual, well, maps that turned me off of it after a few weeks.

In the UK Apple Maps doesn't tell you which lane you should be in before turning. Google Maps does, which makes a huge difference when driving.

When driving I usually use Waze, which doesn't have lane assist and prior to this I used to use a paid version of Tom Tom which did. Don't think it makes a huge difference to me either way.

Having just traveled through the Glasgow, Edinburgh, and London, I can say with confidence that I would have appreciated lane guidance greatly for the 7 million roundabouts I went through.

I didn't know google maps did this or I would have used it. I was using Waze instead, as it's my default.

The website version of google maps is pretty much unusable on an iPhone, I briefly installed the mobile version at some point, but I felt like it was less well integrated overall, so I uninstalled it.
