Sanji being created with gene mods could very well explain most of sanji's stranger abilities, and when it comes to niji beating him up,  i'd say they could be evenly matched if it weren't for them threatening zeff and using explosive cuffs. I'm looking forward to how reijiu's allegiance will evolve throughout the story arc, seeing how she wasn't as cruel as her brothers and father in the past, and seems to have at least some respect for sanji's power-up since. Perhaps Sanji isn't the only one that inherited some of their mother's traits?
