Looks damn important
Personality damn important
Compatiability even more important.
Verdict? 
Looks cannot help to manage relationship. It simply satisfy
nature's behavior. (Masculine energy attracts to femanine energy
and vice vista. Pretty and handsome has deeper and stronger
vibes).
Personality varies with different people (for ladies, different
time of the month as well). Generally, people have not much of a
problem with personality (this is shown by people having more
friends than enemies/people dlsliked). Acceptance and keeping an
open mind makes things easier.
Why compatibility most important?
You can have a damn good-natured, loyal, faithful pretty girl,
together with a SNAG, decent, boyish looking guy and the
relationship still dies because of incompatiability.
You can have road-kill face or awesome looking
ones, sh|t personality or great ones, yet your relationship fails.
This is because at first glance, subconscious love desire seeks for
similarity in personality. When it has it, later, (likely when in a
relationship already), it seeks for complementary personality - in
simple, what I meant is that their characters have to complement
one another, filling each other's flaws with their strength.
Personality is one person's effect, compatiability is two person's
result. That's the difference.
