I suspect the overwhelming vote here will be for the Roland
However, I'd spent ages trying to like any Roland or Yamaha or Casio and eventually decided I could put up with any of them probably.
Then in another part of the store I saw the Korg C1 Air, tried it and instantly loved it. Felt just right, sounded beautiful, nice display too, which is unusual for the price. Even has the little headphone socket so you don't need an adaptor.
Headphone sound was superb.
Anyway, played it several times over a couple of months to be sure, and decided to buy.
At the last minute, on the final test in the store, I noticed that when the key cover is open, it projects a few inches past the vertical, so I'd need to put it a few inches away from the wall rather than flat up to the wall like I'd intended.
That became a deal breaker for me, and I've since looked round again, trying to like something else.
Then this morning I was trying the Casio Privia PX-870, willing myself to like it.
While I was playing Bach Prelude in C on it, a nice lady browsing the sheet music even smiled at me and said Very Nice
Then I stood up, sidled over to the Korg and sat down.
I'm buying it and going to stand it a few inches from the wall!!!!
What I'm saying, in a roundabout way, is I'd find a way to try it if I were you
Their stage pianos are well respected and I see no reason why the C1 Air should let me down.
