Mapbox are killing it with awesome OSM renders. Their 'Mapbox Streets' you can get if you use their API is amazing (better in some ways than Google Maps) and they also have a quite nice open source style called 'OSM Bright' that you can use on your own render server.
I would like the default style on OSM.org to be a bit nicer, but the problem is that that site is designed more for editors than users - the point of that map is to try and show as much info as possible - half the battle to get a really good looking map is getting rid of information you don't need to show.
