@DaReaperMan The idea that humans weapons in Bayverse is stronger because they are reverse-engineering from Megatron is headcanon of course, but like I said in my previous post, the writers in the first movie did give an excuse as to how humans can hurt TFs with their weapons, as it had humans explicitly switch to incendiary sabot rounds halfway through the movie since TF metal reacts to high heat penetratives. So, I wouldn't say Optimus and other TFs getting damaged or fodderized by human weapons is overall an anti-feat besides it showing a weakness for heat.
Also, besides the military wankery, in the Bay movies, it is rare for TFs to get damaged by mundane things like boulders falling on them or them falling off cliffs etc. Compare this to the Bumblebee movie where TFs were shown explicitly getting damaged by things like falling off cliffs (Bumblebee dropped off a cliff by Blitzwing) or by getting rammed by a small ship carried by water (Shatter's death scene). That rarely, if ever, happens in the Bay movies.
In my view, low-end interpretation OP is multi-city block. High-end is small city. I wouldn't say the small city rating is condradicted a lot in the movies.
Universal OP is wank tho of course.
Edit: Also, besides re-entry stuff, in the first movie, you have stuff like Blackout noselling his own weaponry.
