People might say Dejdamrong is better, but Rambaa's wins over Noboru Tahara and Masaaki Sugawara are better than anything Dejdamrong's done in MMA. People forget (or are just unware of-) how good Tahara and Sugawara were in their primes, but that's another story. Then you combine his wins over Masayoshi Kato, Hiroyuki Abe, and throw in his wins over 10-3 flyweight Ryota Uozumi, Robin Catalan (Dejdamrong's latest victory), Ulysses Gomez, and even Takuya Eizumi [he's inconsistent, but he's better than his record suggests-- he started out going 6-2 with six knockout victories, which's rare for flyweight, and challenged Sunabe for the inaugural flyweight King of Pancrase, and he was a top-10 strawweight for a minute in a short-lived comeback that culminated with
this gif], and he's definitely more accomplished in MMA. To give a frame of reference, Roy Doliguez is Dejdamrong's best victory. Doliguez is a very good fighter-- he was a top-10 strawweight at the time and had avenged his lone loss in MMA, and I like him a lot, and he's a better win than Yago Bryan, who Doliguez knocked out-- but Abe and Tahara were both ranked like 2nd or 3rd, and Sugawara was a top-10
flyweight.
Rambaa also apparently revolutionized the use of the spider-guard in MMA against pretty legit grapplers (Hiroyuki Abe's a very strong wrestler, and Tahara has a really solid submission grappling game) and laid out the blueprint for how you can apply
real Muay Thai to shootfighting. So he's got some influence outside of just his victories, too.
The ONE strawweight world championship
is a more prestigious title than the Shooto title is, so that factors in, but not by enough to break the #2 spot (maybe #3 depending on where you put Wiratchai.)
