Megatron should win. IIRC he and Optimus where leveling mountains with those sabers.
Barely heard of this series. I havent been much into Transformers since RID. I felt the quality of the show shot down. Nothing had been as good since Beast Wars. But I have to say just going off that pic, this one looks good. If this Megatron can beat Whitebeard that's pretty major. Out of all previous versions only Cybertron Megatron had that power in my opinion.
Speaking as a transformers fan myself, Prime is a masterpiece IMO and i highly reccomend watching it. It has the a quality storyline that hasnt been seen since beast wars and top notch animation
Now, as for th battle, heres feats for megatron:
The above videos showcase his raw combat prowess without the help of the dark star sabre. As for his coveted blade, here is a look at its power:
Optimus uses his own star sabre to slice a mountain in two
And here Megatrons Dark Star sabre proves to be superior to Optimuses in power as Megatron suceeds in shattering Optimus's Star Sabre in a head to head duel to the death, proving his deadly proficiency and the godlike power he weilds with such a wepon at his disposal
Oldboy is a perfectly serviceable and unremarkable Hollywood thriller. This, incidentally, makes its existence all the more pointless.
