Hot take, systems suck
Not all system storys are bad but the majority of them are and its because of the system.
Systems can range from simply having a game interface to basically a personal Ai assistant. They are supposed to act as a golden finger for the main character, key word supposed to. Often a system acts as a diamond spoon more than a golden finger. Does the main character need a heavenly cultivation technique? How convenient that it the reward for completing a mission. Or its a purchasable item in the system shop. It completely ruins all stakes or struggle in a story.
systems cheapen any and all accomplishments. When I read that an mc has killed a great monster it just, isnt actually fun when they have no struggle and they just get rewarded with the drops from the monster. I do wished more authors put in thought on how to dismantle a monster for parts. The romance/favor systems are the worst because most of the time its literally brain washing and not just building relationships. Even then, knowing exactly how much someone trusts or loves you is inherently a power imbalance and manipulation.
System stories can be good. though a good system is one thats actually like a game system and isnt just a personal Ai assistant. For example stories like god of fishing, and solo leveling have decent systems. They would be better without systems but the system doesnt ruin the story. Systems should exist to give the Mc a cheat skill like a crafting hub or just knowledge of their health. I feel that system stories have evolved into just, the author's cheap and easy way to make the mc powerful.
There are decent system stories but I have not yet found more than a hand full that are actually worth reading
