Never said I had owned all of these keyboards. The topic was best arrangers in 2020. I have had Yamahas, Korgs and Roland but never had Ketron. This is my list based on experience with the brands and demos only in the case of Ketron. For the sounds I like, I pick Ketron with Korg a close second. I have Genos above the E-A7 because it obviously has more features (better screen etc.). I picked the SX900 based solely on the fact that so many here seem to like it. I never bonded with Yamaha myself because it is missing a fingering mode I prefer (Uncle Dave and others have mentioned this).
