In my opinion, the French League is one of the weakest leagues among the European leagues. The quality of football in this league is not very high, the players and teams are below the Champions League level.
For a few seasons PSG performed well, among the other teams there was no team that had a chance of winning the title, perhaps they have not been very successful in the last 20 years. The 3rd and 4th teams in the Champions League will be easy opponents for other teams

The French League is absolutely nothing compared to other standard league with fierce competitive race amongst themselves. Ligue One have only entertaining features but when it comes to the real deal, they snapped out of it because they're incompetent to face major clubs. For instance, in the UEFA Champions League, we all know what always happen to Paris Saint-Germain failed attempts in numerous times. They've tried and tried until they get no hope left. Perhaps it doesn't mean they will give up but continue to make attempts because winning is sure.
In my opinion, League 1 is not the weakest league among other competitors because there are still several leagues that are weaker, but compared to the top 5 leagues such as Serie A, Bundesliga, La Liga, English League and League 1, yes, League 1 is the lowest league because have competition that is not very competitive, apart from that, they also do not have the financial support, only PSG is the most striking among the others, so it is very natural that League 1 is left behind, maybe if they have the same finances as PSG and can recruit star players, most likely League 1 This will be on par with other top leagues and can compete competitively in the Champions League.
It is recorded that the only League 1 club that won the UCL title was Marseille, but that was a long time ago, even PSG, who dominated League 1 for years, have not been able to achieve results like Marseille
