The Loud House is the equivalent of Spongebob in terms of quality and viewing. The first two seasons of the show are amazing with likable characters, great comedy, and good morals. The third season was decent , but no where as good as the previous seasons. Then after the third season, this is where I stop watching. The newer seasons aren't that good. The stories are redundant, the characters are different, and the comedy is not that good. It feels like the quality and comedy took a downgrade at the fourth season.
That being said, the show is still good. However, the show overstayed its welcome like Spongebob. Even though the newer Spongebob is a bit more watchable, I'm not sure if the Loud House will improve again; but, it may happen. Either way, I recommend the first two seasons, and maybe the third season but only like several episodes. The show is good for its run, but I prefer the old seasons.
