There is also the MapTiler OMT style for OpenMapTiles, which uses Vector Tiles. It is a close copy of the Standard OSM map style. It appeared at the same time as Shortbread on the osm.org website.

I agree, it's super close to the classical OSM style, but some things are missing, e.g. roads that are currently planned or in the building phase.

Yes, buildings under construction aren't there yet either. OMT is OpenSource though, so you can make a pull request: https://github.com/openmaptiles/openmaptiles

Yeah. MapTiler has much better styles in general.

The lack of boundaries below national level is off-putting. Both the style and the tile spec itself seem to need a lot of refinement... highways look like a patchwork at low zoom. I had also thought shortbread excluded a lot of POI types, but maybe I need to review again.

But that's not to diminish the accomplishment overall here for the OSM page itself– this is an awesome step forward!

OSM has always overdone boundaries in my opinion, the raster tiles show national/international waters and electoral districts, which are of limited use for most purposes.

Yeah only motorways are highlighted everything else is faded in background.
