Pre-1996 Undertaker was very much like Kane at his peak in 1998, except between the years of 1993 and 1995, Taker was at a loose end and not as fearsome. So, I don't think it's beyond the realms of ridiculousness to look to Undertaker's feud with Yokozuna in 1994 as a pointer here. Now, Yoko may have won, but ultimately their match at Royal Rumble literally has more interference than any other professional wrestling match ever, and even then Yoko only narrowly won. In my eyes, Kane has this, and I think he's the bigger name overall anyway. Yokozuna looked interesting, so he was given a run, but outside of that he was largely ignored by the wrestling audience. Kane wins here.
I like this argument a lot. Undertaker was CLEARLY dominant against Yoko too, the overall record being 128 wins for Undertaker, 17 wins for Yoko. Fair enough most of that was house shows though, Yoko won their only match on Raw and they traded casket matches on PPV.
I do think that Yoko is kinda underrated. Dude came in, won his first Royal Rumble and won the strap in the Wrestlemania Main Event. How many do that? Sure he lost it to Hogan, but with better preperation he won the rematch, albeit in a crooked way... but he also kicked out of the f legdrop that match! That's being put over in a hugeeee way - the only other guy that had kicked out of it on WWF TV being Sid at Mania 8. No one else would in WWF/E until The Rock at Mania 18. This isn't mentioning the fact that he held his second title for 280 days. Other than Nash, no one held it longer until Cena in 2006.
So yeah, people sell Yoko a whole lot short, but this is Kane who is also a beast and one of the few in the tournament that can handle the power of Yoko. I'll look at both their records against similar sized opponents - obv this will be limited for Kane.
Kane
Vs Big Show - 33 wins 31 defeats w/ 12 draws. At PPV 2-1 to Kane
Vs Mark Henry - 10 wins, 4 defeats w/ 1 draw. At PPV 1-0 to Henry
Vs Vader - 24 wins, 3 defeats w/ 1 draw. At PPV 2-0 to Kane
Yokozuna
Vs Undertaker - aforementioned, got crushed on house shows, 1-1 on PPV
Vs Vader - 2 wins, 6 defeats. 1-1 on PPV
Vs Kevin Nash - 0 wins, 14 defeats.
I guess I've gotta give credit to the argument that Yoko's success was largely based on the lack of powerful members of the roster during his prime, while Kane excels against guys that weigh more than him. I'm voting Kane, bad draw for Yoko. I'd take him over a BUNCH of average sized guys
