We kinda know the answer to Yuji vs denji in terms of speed
In their video with mahito vs shigi they scaled mahito with BF amp to Mach 900+, dumb ass shit I know but in reze vs bakugo when they were wanking the shit out of reze they scaled the gun devil to Mach 500.
So yuji either EOS or Modelo would be upscaled to high hell because EOS yuji or Modelo Yuji would soeed blitz and vigorously Rail mahito lol.
