This is not a question on what style each person practices, although the style will determine some aspects of your fighting. What are you good at in a fight? What do you look for as far as openings that you are good exploiting? What are your weak areas?
I'll give mine. The system I practice is ideal for close combat. Because I am fairly big, people try to stay outside of my range a lot, so I usually find that the fight starts with some long range kicking. I like to enter most from when my opponent and I are parallel in stance. Sometimes this means we just end up parallel, but I also pivot a lot so that we end up parallel, then step 45 and straight into them, watching for a kick as I enter. If the kick comes, its chin na and a step back to unbalance. I aggresively go after the rear leg, and once the opponent is starting to become accustomed to that, a flurry of face/body shots. Always attack attack attack! I look for openings to the ribs and try to get the opponent to devote to side kicks, as I like the practice at hooking them.
My main weakness is my relative inexperience and my devotion to my art. Because most of the tactics I have developed so far relate to the parallel stance tactics, other areas are still to be developed. I am at a stage where my fighting is devoted to catching the opponent in parallel, as that is my cue to enter. As far as my devotion to my art, it is not a serious limitation, it is just that I am single-minded in using the internal stuff in my fighting, and I do not know the whole system yet, so as I learn new things, I incorporate what works for me, so there are things yet to learn that will fill gaps in my fighting.
