Hi Ton :
An easy question but a very difficult answer though.😱
I am a Tyros5/76 arranger owner. I am very happy with this great instrument but who am I to tell you which choice you have to make ?😻
I am convinced the new range of keyboards like the Genos and the SX serie are very nice, modern arrangers with a superb sound.
For me there is no reason to upgrade but other members of this forum have a different opinion and they are making an other choice ... that's the way it is and each opinion should be respected, IMHO.
You are the only decision maker.
All depends on your personal needs, taste and budget.
Take care, Babette
