[Neku Sakuraba]

Looking at both of the Reds (Manga and Game), they are different. In the game, Red is different from Ash in the obvious reasons. Red doesn't say anything and their clothing. But, I find Red to be very different from Ash other than those two differences. He manages to defeat the Elite Four and become champion, then moves on to Mt. Silver, ready to defeat anyone who comes. I would be much more afraid of Red because of his more versatile team consisting of all the starters, a Lapras, a Pikachu, and a Snorlax. Whereas Lance has only Dragon-type Pokemon, which are defeated more easily by other Dragon-types and Ice-types. I think I might be going too deep in...
In conclusion, I believe that Red is stronger and would make a more dangerous enemy if he was one.
