I decorated basically half of my house in johnstones aqua 2 years ago, whole reason of going for this was to avoid the yellowing of oil based paints. Unfortunately since then I know more about johnstones and it does yellow.
I purchased bedec aqua advanced and this is so perfectly brilliant white, also has a really nice sheen. The application I find to be an absolute pig though, I'm no stranger to decorating and I'm using worster brushes, the finish is terrible in comparison to johnstones. Brush strokes everywhere and the stuff is so thick and dries so fast that your brush drags.
I've heard good things about dulux quick dry gloss, but open to any others I could try.
