Laundry Day is my favourite SP so far and I highly recommend it if like me you enjoy playing families and have the Parenthood GP. There is just something really satisfying about watching my sims do their laundry. It is also one of the largest SPs with lots of nice CAS and BB items, as well as gameplay. Toddler Stuff is another of my favourites and a must have if you play a lot of toddlers as it gives them much needed CAS and activities. I really enjoy taking my toddler sims out on play dates to toddler parks.
My First Pet gets a lot of hate since it really needs the Cats and Dogs EP to fully appreciate it, but I like it. I don't dress up my pets much, but I really like the hamster and BB items, which work particularly well for younger sims. I have mixed feelings about Fitness Stuff as I was disappointed we didn't get dumbbells and/or exercise bikes and instead got a huge climbing wall that I rarely use. I like the earbuds and workout videos though. Moschino is probably my least favourite of your choices since I'm not keen on having brands in my game, but the CAS is tasteful for the most part and it does have some nice BB items, as well as a photography update and freelance career. As others have commented, the best SP for you all depends on your play style. I recommend checking out the SimsVIP guides and other reviews if you haven't already done so to see which appeals to you the most.
