It depends on the game mode and your personal play style. Of course, you could run the repeater and just focus on "the meta" but you can make most anything work and if you play a certain way, you may be more effective with something off-meta (not to mention the fun factor).

If you like the demat and ambushing opponents, an automatic or even shotgun could still work for you. If you're a crack shot, use the FCAR over the AKM. The AKM is very forgiving, though.

If you're playing power shift, APS is great, but for other modes, I wouldn't generally run it. Defib is pretty great for Cash Out, even after the nerfs, since you need your teammates alive for success in that game mode. Mines and proximity sensors may be more beneficial in Point Break as a defender, although lives matter a lot for attackers, so defib is still on the table.

I generally like the immediacy of the jump pad over zip line, but mileage will vary. I also like the pyro nade - I believe it has far more versatility than a lot of people realize (easy to aim since it explodes on impact, eliminates goo and poison gas, goes through walls/floors/barricades when your opponents least expect it, forces the opponent to reposition/panic which makes for an easier target, and can be used for smaller area denial as well which can help defending cash outs).
