I gave up on Google Maps a long time ago. On my desktop or laptop, it loads in chunks. Like, the map loads, then the search bar loads, then the navigation (zoom tools, etc) loads. When I click and drag, many times I end up selecting the page instead of moving the map because it hasn't finished loading. I use Bing Maps on desktop and Apple Maps on mobile, only using Google Maps when I need to verify an address is the right place or find a company's hours, since their data is better than their competitors.
But man their performance is worse. Way worse.
