there is just one thing VEGETAM that you seem not to understand about DBZ...
i will just say, don't get down to just what you "SEE" but have caused that to happen !

example:
goku trained under 100x gravity = true
but he also started at normal gravity then get up little by little or his body would have been crushed too bits

so, "IF" ryu had done the same thing then he would have the same strenght as goku had after that same training !

now, onto the "KI" thing...
this has only a STRENGHT base !
what does that mean ? simply that akira toriyama used THEIR KI to "ENHANCE" their own power. meaning that "IF" we get ryu to have that much ki he could be as strong as goku. now akira has made their ki going stronger not their actual strenght. while goku has a ki oversized, ryu has a normal ki. so he cannot rival goku in the fact that goku has KI to make him win !

conclusion...
only techniques can be compared cause the creators have made DIFFERENT universe for them ! Goku's universe make KI going stronger not their actual strenght. ryu's universe is more REAL cause it is actually based on pure strenght ! not ki ENHANCED

but that's "just my 2 cents !"
oh no, now i'm talking like TarkanX

EDIT:
another example of what is said here...
VIDEL'S history
she was like a normal Fighter, as normal as ryu or zangief, but then gohan teached her what KI is and how to use it... what happen after that ? she gets stronger and stronger !

now her father "IS" the stronger "HUMAN" fighter on earth. so i really think he can beat ryu cause "THAT" would make a great fight since both know how to fight and they are normal ! but then ryu would be able to project fireballs and mR satan couldn't so ryu would have an advantage here !

that was my theori about how come we can't really compare 2 different universe !
