Since most other Cherries have already been picked and adressed, I'll add one that is debatable, but a Cherry in my eyes:
The Re-Engineered Large Laser since the rules changed to make the RE Lasers semi-pulse.
And it's the Large that stands out and imho takes a spot alongside the regular Large Laser and the Large XPulse Laser. Why? Take a good look at the stats. You get weapon that has the range of the Large Laser, with the damage of the Large Pulse/XPulse, and only a slightly worse heat balance/damage balance than the regular Large, the same as the Large Pulse, and a way better one than the Large XPulse.
Sure, it's one ton heavier, but if you wanted the same -1 to hit on a Large Laser, you'd need to add a 2 ton TarComp. The only real downside is the large size, but you get a bonus for it that gets ever more important with the proliferation of Reflective, Ferro-Lamelor and especially Hardened Armor.
If you have the crits free, the LREL is arguably a better choice than the LL and a much better choice than the very heat intensive LXPL.
By the way, it's easy to see what exactly is "OP" or "wrong" about the Clan LPL... take a look at the range bands of the three regular Clan Pulse Lasers:
SPL: 2/4/6 - 2 Hex steps
MPL: 4/8/12 - 4 Hex steps
LPL: 6/14(!!)/20 a 6 Hex step(as it should be) followed by an 8 Hex step and then another 6 Hex step. See?
Now, if we apply the band pattern of the other Clan Pulse Lasers to the CLPL, we get a 6/12/18 weapon that does 10 damage. In essence, an IS PPC without minimum range and with a -2 hit modifier. That looks much more acceptable, don't you think?
