Okay. For controlling stability you just honestly have to master it. Also, a HC wIth good stability is never a bad choice. Like The Devil You Know has good stability and has the ability that when you cause damage you increase your stability. Also you have to time your shots. HC can drop people in 2-3 shots. As for play style they definitely favor a more non aggressive route. You won't be someone with an auto rifle at close range unless you can get quick head shots. But you really need to practice predicting the recoil and aiming for the head. A lot of PvP kills will be headshots because they get like 80-90 damage depending on how much impact the gun has. You also have to be cool under fire. There have been countless times where I've engaged an enemy close range and won because I kept my cool and got quick headshots. Additionally strafing while shooting will also come in handy
