Going around what to do?

There were two rationales given in this thread, and both of them make
sense to me... but which one would you say is more correct?

a) stay to the right to make it easier to see the traffic (sitting in
the left seat),
b) stay to the right to stay away from the pattern (and away from the
departing plane's presumed crosswind turn).

The reason for asking, of course, is what should you do if the pattern
is RH - sidestep to the left or right?

I've only had to go around for traffic once and it was a weird
situation. I was cleared for T&G on 31. 28 starts to the right of 31,
intersects it, and obviously continues to the left. I was on short
final when tower cleared someone for takeoff on 28; he started rolling.
Since i wanted no part of playing chicken at the intersection, I
immediately went around (then announced it), flew the centerline and
probably the tower gave me right traffic to stay away from the
departure end of 28. The other guy's takeoff clearance was not
canceled, and he departed.

At the time (pre-solo), I was a little rattled, the tower said "sorry
about that" and my instructor said I did the right thing. But, after
reading this thread, it made me think about it some more, and I realize
I likely did not keep the traffic in sight and in fact may have passed
directly over him at some point (certainly a possibility even if it
didn't actually happen that way). So, now I think perhaps I should
have done something differently, but what?

Not crossing 28 would be difficult at best (the airport is KAGC if
anyone wants to look at a diagram) - for one, it's going to involve
really low altitude turns - no way you're missing the approach end by
turning right, and if you go left you're headed towards the hangars and
tower. You're also not going to have a lot of choice about your
airspeed during the initial stages of the go-around. So what to do? I
know now that a 172 should easily be able to land and stop before the
intersection, but even now (a whopping ~25 hours later) I wouldn't be
entirely comfortable with that...
