Honestly, I have some files where everything is easy, and some where it's all really hard. Depends on how I'm playing.
As for the debate comparing it to other genres, I prefer Sims 4 for graphic style and game play. I don't really want to get into a back and forth debate and sadly EA doesn't pay me to be their Sims 4 spokesperson and sell it to others so I don't think I'll bother going into the specifics right now. It's simply a matter of personal taste and it doesn't bother me if others prefer Sims 123 as long as they don't force me to play haha!
And now as much as I'd love to play Sims all night, I unfortunately have to get to bed so I'm not too tired in the morning for work. (You know, that place I have to go to so I can afford to buy the next expansion ;) )
