Google Maps is less cluttered because it's displaying far less information. In the Sochi example, take a look at the park to the left. OSM displays all the footpaths in the park, Google Maps display none. This is a running theme: all the red dashed lines are pedestrian rights of way that Google simply doesn't know about. What if you wanted to cross the railway line on foot? You'd be out of luck with Google Maps... And while we're looking at the railway, notice anything missing from Google Maps? Only the largest road (looks to be a highway) on the map! It seems like this is new and has yet to be added by the Google Maps team. OSM has been shown to have more detailed data for many Asian and European countries (like Russia, in our example) than Google Maps, and this serves to make those maps "look more cluttered". But if I was visiting Sochi, I know which map I'd rather be using.
