Shinji's Cero was pretty close to Grimmjow when he fired his own to counter it. In the anime, it looked to me like it was so close that Grimmjow's Cero didn't get the time to grow big enough to prevent him from getting injured. But that could just be me.

Similar, it could be that Bazz-B used too little flames to completely protect himself from Yamamoto's flames. Or he could have used the majority of it to protect Äs and NaNaNa since they appeared to be closer and could get more injured, but such an act seems unlikely for someone like Bazz-B. But seeing as Yama only used his Shikai and most likely didn't go all out, it seems Bazz-B's flames are much weaker than Yama's. Something I also expect.
