I'm a bit conflicted with vector tiles. I haven't found a good combination of style and tile generator (schema) that provides the same level of detail as the original raster tiles provide.

The article has screenshots that very much demonstrate this difference. The first screenshot has, for example, a lot of POIs (statues, shops, theaters, viewpoints), highways that are different when they are bridges, different colors for grass vs parks, different line widths for different highways, sports fields, building and neighbourhood names, arrows denoting one-way streets, building parts, stairs, trees, and a lot more.

The second screenshot has none of that, aside from a single trolly station and a single street name (which is also rendered incorrectly).

I've tried a lot of vector styles (all openmaptiles styles, the base protomaps styles, all mapbox styles) and generators (protomaps, openmaptiles, mapbox). None of them come close to the amount of detail as the raster OSM tiles while still being as readable.

I've never found anyone as bothered with this as I am. Vector styles are cool as they zoom and pan very smoothly, and their style is fairly easily editable. But, for any map where you actually want to see map data instead of using it as a base map for your own data, vector maps fall short.

Maybe it is just because of computational limits. I can imagine that displaying the same amount of detail as the OSM raster tiles would require too many resources: both on the client side and for tile generation.

It would be nice if OpenStreetMap would try to mimic their raster style closer, instead of providing just another low contrast, low detail base map. I hope this release of open vector tiles will facilitate more detailed vector maps!

I agree with you, but I go one step further: I am disappointed by OSM raster tiles and especially Google's digital tiles because even they show barely enough information, if you compare them to old style printed street directories. I think they also have a tendency to avoid crowding by omitting important things in busy spaces and showing useless things in empty spaces, whereas the correct thing to do is to show the important things in the busy spaces precisely to indicate that they're busy spaces. And I think there are better things that can be done than just showing trivia if you consider the local area (e.g. a private tennis court might be better off not shown in especially if there's not a great density of mapped objects, but perhaps it's relevant at a resort).

But that's a lot of work, and whereas it's easy to add extra trivia to OSM it's much harder to add extra detail to tiles.

As Doctor_Fegg has pointed out further down, the OSMF provided raster tile service on openstreetmap.org is primarily intended to provide fast feedback to contributors and not for general purpose use, in particular not as a competitor to google.

The whole point of OSM is that you can take the data and build / design your own things. Yes it would be nice if there were multiple viable google alternatives based on OSM and other open data, but that is likely just a pipe dream, the economics don't really work.
