depends what your goal is
for money, just stack as many traits as you can (the extra capacity trait helps here and aunt potential in the late game)
for seduction (getting into their pants asap), i prefer the +love / +sluttiness traits. helps me get in their pants a minute after meeting them. "hi! 3x small talk, compliment if possible, persuade to take 'love drug', bang bang bang"
for energy drink (+nanobot, permanent stat increases like +sluttiness/+happiness)
as Elkrose mentioned, suggestibility is also super helpful if you plan on putting girls into trances often for permanent stat changes
PhalzZ if you have a task for the frosted cupcakes but can't get boobjobs... maybe try doing a private lapdance with a stripper. if she's slutty enough she'll let you cum on her tits (about 30 or 40 sluttiness needed iirc, possibly less if she has a cum fetish). another alternative (i think) is if your employee goes to the training seminar and is slutty enough to give you a bj to thank you for the seminar. she'll typically let you cum on her breasts since she doesn't want to ruin her makeup (as long as she doesn't love swallowing cum)
