Because I am not the "typical" guy, I would just stick with staying my own gender and staying me. Plus, my graph making is kicking in... so I will make the pros and cons of being a girl and being a boy. This is just my opinion, but I think it is pretty accurate.
This is only the "average" traits though some people are the exception to a few of these.
Pros of being a boy: Um, there is one particular pro and con I am skipping... it is understood though. So moving on, you do not have the pain of child birthing (yes, I said child birthing). People seem less sexist towards men, at least from what I know.
Cons of being a boy: You mature later on average (not physically... though true. I mean mentally), most boys I know do not really comprehend the fullness of life, they are more prideful and have more of a if-you-can-do-it-I-can-do-it-better type of arogence.
Pros of being a girl: You are smarter (on average), you will likely be favored and get things as a child (that is not a average... it is practically a fact), you are naturally neater (and don't get teased when you are neat) You are a LOT less prideful, but seem less secure in yourselves. more rational
Cons: um, pain when you give birth, More sexist people against women, girls seem to gossip more though I think both sexes are bad at that, Less security and less of a strong mindset (I see girls break down quicker then guys).
Now, there are exceptions. My sister is probably the strongest girl I have seen (physically and mentally). I also now one very secure person in themselves (who is female). And I am actually very neat and I have a deeper thought pattern then most guys my age.
Sorry for the terrible grammar, but I typed this in a hurry.
