If mechs have an abundance of weapon hard points most likely you should go brawl, because brawl -> high DPS -> Easy KMDDs.
For those that can't brawl I suggest:
Panther with 3LL
Dragon 3uAC2s
HGN IIC has a variant that can do SRM6+LB20 but let's face it that like an Orion IIC but slower and larger I prefer this little jewel from the past:
This thing was imo the second best assault mech back when KDK 3 reigned supreme, it had awesome quirks and both uAC10 and LPL were better than they are now, there wasn't much talk about it because everybody was talking about KDK 3.
Then it was nerfed, PGI was mostly targeting other mechs but this one took nerfs from all sides until it was sent back to its DOA status it had achieved promptly upon release. And so it rested forgotten in the hangars of the few of us lucky enough to have lived the brief time when this mech reigned the battlefield, (almost).
Well turns out since that happened (about 2 years ago) as the mech slept the dream of dead mechs many things changed that have brought this mech back to life, LPL was improved a bit, uAC10 benefits from skill tree, other mechs' range quirks have generally been nerfed significantly, as has armor quirks across the board and finally this mech is widely regarded as bad one and received very generous agility stats, it turns accelerates and brakes very good for a 90 ton old lady.
All in all if you can't play the KDK 3 because how poorly it handles you can play this thing instead to get a feeling of what it used to be piloting it. It is a solid mech, fun, deadly at mid range, shields well with its enormous arms and twists fast enough to actually do it in compass with weapon recycling.
EDIT: Just after I wrote this message I played one match because I still needed 1 more KMDD, turns out I over did it a bit:

No consumables were spent.
