I like Kikuchi (ranked him 49), I think Kikuchi case kind of struggles because a big showcase lack of footage only having a maybe 12 year very good to great period 1990 to 2003 (I could be wrong).
I ranked Fuchi at 22, I think depending on someones enjoyment for the AJPW dad tags (which I really enjoy). There's a case that Fuchi was fun to great+ 1981 (him in CWA) to 2024 (having the great match vs. Yuma Anzai) with those matches being more accessible with AJPW streaming and coming thanks to the GAORA youtube channel
I also think Fuchi's presentation made him easier to lift opponents I find less interesting to stuff I enjoy (Misawa and big match Kaz Hayashi) and also got more opportunities.
Kikuchi does peak higher though with the Ken Ohka bread match, the 6/1/91, and 5/25/92 with Kobashi vs. CanAm matches but, he is also with one the greatest wrestlers ever es I especially in tag matches. I might to check out more Kikuchi's work try to close the gap.
