Werewolves is the one must have on your list for me. It is really well done and it's still as much fun two months later as it was on day one. It's also one of the least buggy packs in a while, and is one of my all time favorites. I'm a bit of a werewolf fan girl so I am biased.
Of the others, I'd go with Dream Home Decorator. I think the BB is great and the CAS stuff is fairly good too. The interior decorator career I really can't say much about because I've played it twice and not for very long. It's one that I keep saying I want to go back and try but I haven't so far. What I did see of it felt like it would be fun if I was in the right mood to take it on.
I love Tartosa but I'm not sure I'd recommend MWS just for that when there are still some better packs that you don't already have. Even though HSY fits your style the best, I'd give it a bit more time for patches and mods to fix it up. I have a hard time figuring out how many of the bugs were the fault of the pack or that train wreck of an update. Personally I feel like from my own experience with the pack that it's more the update that broke things. Either way I'd give it a couple more months before I came back to it if I didn't already have it. It's one of the rare times I regret getting a pack or kit on day one or soon after. I wish I had waited a couple of months like I did with MWS.
