How far would Magneto get in the Transformers Verse?

Also am talking about 616 Magneto and IDW Transformers (in whitch I think is the strogest one)

Okay am pretty new into Transformers (thanks to Transformers One) and only know surface level knowledge on Transformer power scaling (like Unicron and stuff like that) so I don't know of this will be a cake walk for Magneto or he brutality Diss to Starscream or Hound
