So after all the comments praising the other version I went ahead and read it, after all it was just 5 chapters.
Well, all the whining was completely unfounded. I'm actually surprised how off the mark it was. This version is much better, less rushed, for example MC's backstory: here it's much more fleshed out in a later chapter as a flashback while there it's just a few pages in the beginning, making it feel like a generic OP power fantasy in a bad way.
About the only legitimate gripe (if you hate fun) is this one leans into the humor a bit more. Sure, the translation is also a bit worse, but that is in no way the fault of the manga.
This one has better art too, especially for the female characters and the dragons.
