The EXR-5 plays all V, G, E and EM-series styles. With its own sounds of course. I leave it to your judgement to decide if that's better than the original keyboards or not. I'd convert to VA-styles in EMC.

Your question about the comparison between sounds of the E86/96 and the EXR-5... Well I know what I like best. It's not up to me to decide for you what sounds best.
