Oasys is built like a tank, has quality controllers and a larger touchscreen.
The keyboard of the OASYS-88 is an expensive high-end quality keyboard, custom made for Korg by Fatar. It offers an excellent playing feel and connection between player and sound and is one of the best I know. The 76 semi-weighted key OASYS has an excellent Yamaha keyboard.
The Kronos' RH-3 keyboard instead is based on the former Technics design and is obviously cheaper to produce and the build quality and playability is of course not comparable with the Fatar.
By everything I've read so far on the web, it is confirmed that at least the sample based HD-1 engine of the OASYS and Kronos sound identical in quality. But this was never confirmed concerning the synth engines like the MS-20 EX.
As it is known and confirmed by 1:1 comparisons by different users (like myself), the MS-20 EX (48 voices poly) of the OASYS has the much better sound (and also much more options), than the Legacy Collection MS-20 for PC/Mac.
Unfortunately, I never had the chance so far to make a 1:1 comparison between the Kronos' and OASYS' MS-20 EX, but I had several chances to play the Kronos with my own AKG headphones and I could swear, that the OASYS' MS-20 EX (which I use almost every day) has the much better and more direct and brutal sound (closer to the original), than the Kronos MS-20 EX's, which appeared to be similar to the Legacy Collection MS-20 for PC/Mac.
Hopefully someone will make a 1:1 comparison between the Kronos and OASYS MS-20 EX and post some sound samples on this forum, which will show, if I was right or just biased, because even good trained ears can fail in certain situations..
Finally my recommendation:
If you care more about the synth engines/sound design and less about the acoustic piano (still very good on the OASYS with 0.5 GB waves) and e-piano (still excellent on the OASYS), I highly recommend the OASYS, due to its superior UI. Otherwise take the Kronos, but don't buy the 88 or 73 hammer key version, but the 61 synth key version and a good 88 key master keyboard instead...
