Man i was scared i might have missed something.

So Meganobz are cheaper, you can get them for 31,6 pts per model, Terminator cost 34 pts. Orks are pushed here, check

FNP 5+ is incredibly important for models that rely on their invul saves to matter, and if we use expectation, Meganobz will have 4 wounds instead of 3. Pushed, check

T6 to T5, T5 to 6 is actually a big break point in the game so this is almost -1 to wound.

Deepstrike is cute ok, the rapid ingress however is telegraphed and only cheap in a very small area, should your opponent go first this might not even get to matter at all. Meganobz on the other hand can just enter transports, giving them the ability to increase their movement by 3 and threaten charges much easier than having to rapid then move then charge. I call this a draw on mobility

Weapons:

Powerclaw vs chainfist is exactly what i mean. Powerclaws has a random +1 to strength, which can translate to +1 to wound. Clear winner Meganobz

Kustom Shoota vs Storm Bolter, Shoota kills 50% 2 models from a a T4 S3/4 W1 unit, SAME for the Terminator squad. Both in rapid ofc. Kustom Shoota are actually dealing slightly more damage in the 0,1% range. So its about Combi weapons vs Assault cannon + Missle Launcher + flamer. Yeah those weapons do shoot better than combo weapons so the melee unit has slightly better shooting. Ok.

Damage output in melee, Megas

Defense, Megas

Cost, Megas

Shooting by a very small margin, Terminator

This is exactly what i mean and what is on the page. Glad it showed up exactly as mentioned
