Well, it depends where Oda goes with this, right now I can only comment on things happening right now, I don't know what Oda has planned for Sanji's endgame but getting rid off the raid suit is a good start for sure. But I have to wait and see whether the raid suit is gone for good or not, I'm afraid it might come back in a different shape or form since the "Franky Modification" has been foreshadowed for quite some time, and I highly doubt that Oda would do that for no reason whatsoever. To be honest, I'm not against the raid suit itself per say, but rather the powers it gives to Sanji and what it represents... if Franky manages to create his own version of the raid suit with powers that can COMPLEMENT Sanji rather than undermine everything he achieved so far, by himself, than I'd have nothing against it. But, regardless whether "new or old" raid suit with NEW powers, I'd prefer no raid suit whatsoever.
I have to make a correction here: I'm not against the gene mutation if Sanji awakens it by himself, with no interference from outside whatsoever, while fully maintaining his emotions. But, I'd still prefer no gene mutation ether way, but wouldn't be against it if Sanji awakened it buy himself rather than due to the raid suit (which btw doesn't make any sense at all).
It's a good development for Sanji for sure, but, there's a big BUUUUT. I don't like that Sanji only now acquired "self esteem and self respect" when the raid suit bit him back. But this is post-timskip, so you can't expect good character writing from Oda... overall, it's a good thing, but again, it remains to be seen where will Oda go with this. And the last point: it would've been so much better if we had this in WCI rather than Wano, WCI needed this, Sanji needed this and WCI was perfect for that, + Sanji could have gotten a character development in WCI.
