You Can Only Choose One

would you rather be

UNDERESTIMATE

––––––––––––– or –––––––––––––
OVERESTIMATE

?

this thought came over to my mind unexpectedly right after I woke up from my dream. well it's a bit uncanny, I can't remember what kind of dream that molded this thought, I lost track of it. I personally can't decide whether I'd rather be underestimate or overestimate, both have their advantages and disadvantages. so what about you? which one do you prefer? please spare me your thought, you'll be very welcome :)
