You're right. There are other incarnations.

Here are how all can beat Godzilla:

G1: He can use his brains to plan a way to beat Godzilla. He's quite clever. His ion-blaster can hurt Godzilla. And his energon-blades could pierce the giant's throat and stomach. And his truck-mode can help to dodge.

RID: He can use his super-weapons to beat up Godzilla. And he can use his brains too.

Armada: His super-mode's power weapons can really cause damage on Godzilla. And he can use his brains too.

Energon: Same as Armada.

Cybertron: Same as Armada and Energon. And he could use Vector Prime's sword which he was given to beat Galvatron. The combined power of his relic of Primus with Vector's was able to beat Galvatron who could the power of Unicron. The overgrown gecko would fall.

Movies: Optimus can use brains to fight Godzilla. His ion-blaster can hurt. He can also cause serious wounds with his barrage-cannon (the rocket-launcher he shot Megatron with in ROTF) and his flightpack-mounted rocket-launchers (from DOTM). He can also use his energon-blades to tear the giant's throat and stomach.

TFA: Optimus can use brains to fight the beast. And the Magnus Hammer would knock it down and harm it.

Prime: Optimus can use brains to fight. The weapons of his Beast-Hunter form would cause pain for the giant. And the Star-Sabre, the mystical sword of Prima who led the Original 13, would tear the beast apart like it did to a mountain.
