Bayern have won 22 league titles in Germany. By far more than any other club.
FC Nürnberg are second with 9 wins. They last won their league title in 1968.

The diversity in terms of different winners and lack of gaps between the most decorated clubs is clearly MUCH smaller in France.
On the other hand diversity (read different league winners) says nothing about a league's quality.
In any case BOTH PSG and Bayern have dominated their respective leagues in the past 3 seasons and I doubt that many see that changing in the future thus your discussion is quite silly.
