I ordered a gallon of D114, have never tried it though, but have confidence in Meguiar's. So I'm sure I won't be disappointed.
I have tried UWW+, ONR and Pinnacle with Carnauba.
I would say ONR was my favorite of the 3. Second would be UWW+ and disliked Pinnacle because it could only really be used on paint and at times it still streaked there too.
ONR and UWW+ can be used on exterior/interior, so they were great.
However, Meguiars cleaning ability of not leaving anything behind, plus the price and it's interior/exterior usage made me want to give that a shot.
I'll report back when I've tried some.
