Is OSM that far that we need verification and quality ensurance?

We are still far from completeness, which might be a primary goal.

I checked two of the major federal states in Germany by now, comparing the
data with other street lists (maps, addresses etc.)

http://wiki.openstreetmap.org/index.php/North_Rhine-Westphalia
http://wiki.openstreetmap.org/index.php/Baden-W%C3%BCrttemberg

As long as we got less than 50 % of the most important street names (and
Germany is about 10 %) I do not mind yet that much about verification.

Don't get me wrong: verification is important. But I feel that precision, vandalism (version management) or licensing are equal and secondary goals. OSM may have a major strength just as a good wiki when it offers a reasonable base, while it may be much more up to date than man other sources. 

Is there any comparison about the amount of data within current commercial
systems, compared to OSM?
