I can give you an honest point of view from the enemy side.
If you like very close and intimate, Novas with SPL is a constant menace for IS mechs: fast, agile (JJ), less engage options that a med las nova, but really deadly giving the optimal engage condition.
HuncIIC and Huntsman has (more or less) same pros and cons: not very agile, they suffer being encircled not only by lights, but Mediums too. On the other hand, if the rest of your lance is good at getting attention, you have impressive damage capabilities (Both with ballistic or SRM). If you manage to make your shot to land, they are gamechanger!
Ice Ferrets were a surprise for me: they are fast, can carry valuable weapon loadouts, and, most of all, they are underestimated. And this is very important, because IS tend to target big stuff or novas, and you can have an easy task by sneaking on the back of the mediums and melt them down in short time.
Cheetas are more or less the counterpart of locusts: if you need a fast light, and you are good piloting it, is the first choice.
Shadow Cats? Dunno..sometimes they are scary, some other not. You have to struggle finding the right weapon loadout in conjuction with your lance. Brawling or long range? with the wrong loadout, you are an easy pick.
One mech i would not pick as first choice is the Jenner2c. I see only very, very good players performing with it. It is good to sneak on the back of IS meds and unleash a full SRM alpha, but it is very hard to fulfill the role of a light or a medium, when you have better mechs in the specific roles.
That being said, Have fun and cya on the Battlefields!
