I'm noticing my Sims wants sometimes don't match up at all.
I often play a evil loner Sim, she's been getting wants to befriend random acquiantences or chat to them, which is far from her actual personality. Meanwhile she should be fearing talking to new Sims. I've noticed it best if you have a Sim like L.Faba who can still also often roll to befriend a townie they rolled a want to become enemies with in the past.
I still majorly prefer how the Sims 2 aspirations/personality mixed together because the end result wouldn't involving befriending/woohooing strangers unless your Sim had the popularity/romance aspirations
But losing the pack specific aspirations TS2 had is a huge loss. I miss my enemies often wanting to drink each others cowplant milk or seeing them sprayed by skunks.
