The majority of the time, the first LTR I want is one of these (also Artisan Crafter and Acclaimed Author). But quite often, my sim children will accomplish their LTWs before they age up to teen, and these rewards aren't available yet. So when I know that I've saved up enough to buy the relevant one after the child's birthday, I'll get them Steel Bladder first. Also, if they're not going to be making arts or crafts, Multi-tasker might be at the top of my wishlist (meet new friends and talk to friends become more efficient, even though the "experience" gains are unnecessary in elementary school), followed by Steel Bladder and then Attractive when they age up.
