One of the added benefits of Opti-seal or hyper-seal (beefed up version of opti-seal) is that it adds additional protection and ease of follow-up washing and cleaning. Also, and I've posted this before, they both can be used as a drying aid when doing the two bucket wash and dry method with ONR. It has made washing and drying the car so much easier - and I get the added protection as well.
As far as ONRWW vs regular ONR, I have used ONRWW a lot on my Jeep GC and the new orange version of ONR on the Tesla. I love both. I used gloss-coat (Optimums DIY ceramic coat) so that's why i now use the orange ONR instead of the ONRWW. But overall, I loved the ONRWW and used it exclusively with my Jeep and opti-seal.
