The 5 that I tried with my friends are the CTF-IM (triple AC5 w/ triple med laser), HGN-733C (dual PPC dual Ultra AC5), BNC-3E (dual PPC triple AC5), JM6-S (dual AC20), and STK-M (dual PPC w/ AC20). All these are really situational, and these can all be defeated with different ways. A ton of people complain heavily on these kind of builds, but they really aren't as powerful/OP as people say they are. The Ilya runs out of ammo quickly and usually has XL. The Highlander is really easy to disarm (which was what happened constantly when testing it). The Banshee was either slow or fragile, and STD engines at max go to about 40 kph, while XL engines are easy to shoot off. The Jagermech is really easy to destroy because the shoulders are easy to shoot off. And the Misery is slow and weak for how much tonnage it weighs, so it can be taken out.
The problem with people complaining is that people don't know how to kill these quickly. As a general rule to most of these kind of builds, don't brawl with 'meta' mechs dependent on ammo in general, as they are much better at nailing you close range (Jagermech and IIya examples). Instead, kite them and snipe them from afar. Do the opposite for the ones with PPCs, as they have a 90m minimum range, which could be taken advantage of (Highlander, Misery, and Banshee examples). Aim as a general rule for the legs first (scratch em and check them for ammo and weak armor), and then the right torso. Don't shoot the shield side, as it's wasted effort and ammo/heat. Finish them in the right torso if they have an XL or destroy their center if they don't have an XL.
After testing, I realized that 'meta' mechs are generally very situational and can be taken out quickly when known. I created this topic because I saw that many people, often in nearly every match, complain about how the 'meta' is OP and wanted to address this so some might see it and see their errors in trying to counter the 'meta' or how they're dealing with the game itself.

BTW I was asked by friends to try poptart Shadow Hawks and CTF-3D and Victors with a similar layout to the above mechs, but I didn't really have enough cash in the account used nor did I want to create another account for a public test to test mechs that are already there pretty much. So those were taken out of my test and I didn't use them.
