For live play it is a close call in my opinion.
For Combination of layered sounds you will be hard pushed to beat the Kross 2, this image is of one Combi out of hundreds.

BTW
The Tabs you see in the image are but a few of about 20 Tabs which means the degree of control and customisation if the Programs and Combi’s is very extensive and very easy to access. There is no having to delve down layer after layer in a complex Menu system.
Also the K2 keyboard can be readily split into two zones but by adjusting operating ranges it is very easy to achieve what is essentially multiple splits along the keyboard. I only have the 61 key version yet I have 4 zones or splits in a couple of Combi’s that I have set up for specific songs. Not sure how readily the Yammy or Roly can achieve this functionality if at all.
That said I still think the Juno should be at the top of your list.
Do you research and watch the video tutorials to gain a knowledge of each keyboards Menu, system and in particular good luck with the Yamaha I sort of think you will need it.
Good luck.
