In my small experience, most of the time when I played slow, I lost. And when I played aggressive, I won, but a small pot.
What are your opinions?
For a newbie to poker you answered your own question which is good. When you play slow you are giving more players the chance to get in the hand with half assed hands like 7-9 suited etc etc Each player in the hand reduces your chances of winning the hand obviously so when you play aggressive with them you are doing yourself a favor. A very good poker player once told me he would prefer AK than aces his reason was you know where you stand with AK and it is easy to put down when needed. AA is another story isn't it? lol. Over all i think you are best with playing how you feel like but imo your doing it right!
