G'day mate, I am rather biased when it comes to beards... but I like #1 or 2. ALthough #4 was a really nice picture as well.
At teh end of the day, I think you can pull off any of those looks, it all comes down to what you have preference to, and it sounds to me like you prefer #2 so roll with that! The best part about growing facial hair and the like is how easy it is to experiment.
