I still don't like the raid suit, but I think those examples are wrong. In the Sanji one you used his principles, his pride in change of a power up. You should do the same with Zoro, for example, by not using his sword but still his pride. Zoro swallowed his pride by let Mihawk teaching him swordmanship and the same Sanji did by using the Germa tech.
Like I said, still I don't like the raid suit, because it is something that give Sanji a power up with skills he already has (like why would he care for floating when he knows sky walk?). I mean Sanji could have had a power up with better haki control instead of a suit. I don't know.
