EDIT addition:
I like the "Basic" ballistics the most, cause I find it challenging not only to hit the target in the given circumstances(weither the obstacles would be the range, the speed of the enemy or something else), but it challenges you further when you try actually land a shot on the body part you need to hit to be the most effective.
Add to that, that they are versatile weapon, cause they cover 0-1000(and even more)m range quite well.
I personally think that they are also very well paired with the "Basic" energy weapons(lasers), or, especially, SRMs(but very few mechs allow you currently to pair ballistics with SRMs) - giving your mech not only quite a punch, but making it good on every map and effitient against any kind of weight class mech in the game.
I am prejudiced in my opinions about the weapons that require the least skill, but I gave a word, so I would fufill it.
I think LRMs are the ones requiring the least skill.
I've played with it and so far it's the only weapon that feels like point-and-click adventure with insane punishment for your target.
