Hi Bluebird,
I suppose if your first priority is a good onboard vocalizer, then a psr would suit you better than a kn.
Direct disk function wouldn't be as bigger issue if you were going for a kn2600, because the sd card loads styles and songs very quickly (roughly 3 to 4 seconds) wheras loading the same style from floppy ( kn2400) takes a fair bit longer.(
As for styles and sounds being better on one keyboard or another.
I tend to think it's in the ear of the beholder. I noticed sounds tend to grow on you. The 3 keyboards I had , all sounded so different. I prefer the sounds ( that I use to play melody ) on my kn7 to my ex 9000pro. To my ears , they sound more realistic. I preferred the ( melody) sounds of my 9000pro to my VA7.
As for styles, the best thing to do is try and play both , and see who's styles YOU prefer. Main thing to check is that the styles are going to be useable for you.
Most keyboards have a good mixture of styles, but one brand may do a better job on modern music like rock, pop, ballads, wheras another brand may do a better job of latin, marches, waltzes. If you only play rock & pop, then you'd be more likely to go for the one that does a good job on those styles.
