Daikin Ac are simple but built with best technologies which is really efficient in cooling and energy savings.
1.5 Ton 3 & 5 star both are the or good ones and best in present market.
Further, operation sound level is pretty low and they don’t do any misleading marketing, advertising nor mis-selling to consumers even though their prices are bit high when compare with other AC brands.
I recommend this brand if its comes to your budget when compare with other high price AC brands
