Mr 2 was much easier for Sanji to beat compared to Zoro who had to overcome his limits, furthermore Mr 2's fruit exploited Sanji's non strength based weakeness to women.
A nerfed Sanji beat Jyabura easier than Zoro beat Kaku, and no, a 20 point difference is not worthy of two greater than symbols.
Sanji was more injured, by a lot, going into that fight and Zoro didn't do any damage either.
Zoro is Luffy's second OBVIOUSLY, but there is a large gap there, larger than that between second and third, just like there is a larger gap between Roger and Rayleigh than Rayleigh and Gaban.
