I'd say the only one to fear in terms of Kido is Kagiko...although the grand kido chief title means nothing to him, it's just a title...doesn't mean you are the best at Kido. I mean shit Yama was amazing at Kido, Urahara also yet neither of them had the title. Tessai is amazing at Kido but I mean...Yama is the longest living Shinigami...he knows everything there is to know about Zanjutsu, Hakuda, Kido and Hoho. Despite being quite old he was incredibly fast and strong and he used an incredible Kido to an immense effect. However the Head Captain is likely excluded from these titles as it's a no brainier when it comes to a guy like him. Those titles I assume only apply to those in the other 12 Squads. Then again The grand kido chief title is reserved for the leader of the Kido corps, the Flash title can really go to anyone....although it's mostly disputed between Squad 2 and 6 right now...
Kurisu and Kaizo will likely focus mostly in Hoho than anything else.
Shiro's skill lies mostly in his Zanjutsu which his becoming a shit ton more proficient in
