I play with the whims on, but I find that when I didn't have that many expansions the whims seemed a bit more unique. My first Sims 4 games were the base game and cats and dogs. As I added more, the whims became more uniform, after seasons, all the sims wanted to own a bee box. This kind of continues as I add more, and the Sims have a sameness to them, but I keep them on, because making them fulfill their whim can help turn their mood around.
I had (still have) Sims 2, and even though many wants and fears were similar, each one was ultimately unique to them. I had many Knowledge sims who wanted the same thing, but reacted differently. For example, I had two sims that wanted to see a ghost, one got scared after fulfilling their want, while the other one was super happy with fulfilling their want.
I feel if Sims 4 whims were more unique like wants and fears, it would make the game more fun. Like the whims being the same isn't bad, but the reactions are exactly the same, which is what I don't like.
