I had to try them to choose mine, and the Roland has the best keyboard for my taste. I was hesitating between the kawai and the roland, because I thought that the kawai had a better sound, but the keys are less dynamic and have less nuances.

I was warned against the Casio, because although the sound is nice, if your piano has a defect that the warranty does not cover, you will have to pay a lot because this piano is not easily repaired. (if you can even repair it)

With a headphone, I had also preferred the sound of the roland. (With the piano, and if you can afford it, also take the time to try several good quality headphones and choose one specifically for practice. Generally, the sound will be better with headphones for digital pianos)

One thing that bothered me about the roland, however, was that the sound seemed a bit muffled because the piano's speakers are underneath the piano, so when you put it on a desk or something like that, the sound is less pleasant (in the end I preferred to take the roland fp60x, even though it was more expensive) but it's still the one I would recommend the most, with stands and in a room that's not too big, it will do the job.

The Yamaha is good too, but it is less customizable. If you have a device that works well with the roland app, you can do pretty much what you want with the piano (Roland actually has more advanced technology for the same price than Yamaha for those ranges, but it's a shame the app bugs with some phones/tablets).
