For me, no.

I am not a piano player and I would not know what to do with all the extra keys. There are some portable 88 keyboard pianos with some arranger features. So we are left with an arranger which has a passable piano, or an 88 keyboard that has a passable arranger functions. A 88 keyboard with all of the Korg’s or Yamaha’s arranger would bring the price to not acceptable.

If I wanted both.
A module and a controller keyboard would be my choice – if I played piano.

My last thought. As a purest I do not believe in mixing the instruments, they both have their own beauty. Buy the best you can afford and add module.
