In terms of electricity savings, I don't think there is a huge difference between inverter ACs from all brands; haier, orient, gree, lg, samsung, daikin, mitsu.
In terms of build quality and longevity daikin, lg, samsung and mitsu are no doubt better than the chinese brands like gree, haier, orient, kenwood etc.
I have done some research and realised we can have LG and Panasonic at similar prices GREE is retailing their ACs at, so why buy a chinese brand when can have better.
Go for LG or Panasonic as both are good brands and their inverter model can be had for around 75-80k compared to daikin which is 119k.
