Pfft, if Jaegers popped up in AoT, the Titans would be screwed. The biggest Titan is, what, 60m? Jaegers stand over 80. The Colossal Titan is slow but powerful. Jaegers fly kick giant monsters, and jump and downslam them with rocket assisted punches. Colossal Titan can let off superheated steam? Jaegers have giant retractable blades that get just as hot. Some even have missile launchers with missiles designed to KILL giant monsters.
So what if Titans need to be hit in the right spot to kill them? I'm sure a Jaeger would rip off their head. As for the more common ones around 10-15 metres, they'd either be crushed underfoot or be used as footballs at the Annual Jaeger Rugby Match.
Oh, and did I mention the on board computers sound like GLADoS? When you have giant robots that sound like GLADoS, you know you can do nothing but pray and sh*t your pants. GLADoS was bad enough as some giant computer robot that was only scary because she had near-omnipotent control over the facility she was in. Put her in a giant robot that can use tankers as baseball bats? Welcome to hell, people.
Glad I'm not the only one who saw how similar they were.

I told my brother about it while we were watching and we were all "They should totally use swords, the guns obviously aren't doing anything." And right after I said it they started using swords, just like SNK (imo at least)
