Aesthetically the concealed type is much better. Cassettes make your living room look like a showroom plus they turn yellowish after a few years.

I think it’s possible to create zones even with the concealed type. Besides, unlike cassette type where the vents are fixed to the cassette, one can also choose where to place the vents for concealed type. In my case, the Daikin consultant my ID engaged proposed to place the indoor blower in the middle of my kitchen with vents running parallel on the sides.

Switching either one for a space that requires 5hp might not be a good idea. You might overwork one unit and shorten its lifespan / increase power consumption in the end. I can ask the Daikin consultant (Daikin HQ staff) about cassette single split vs concealed multi split tomorrow.
