Looking for some AC advice.

I went to two different ac shop first shop tell me panasonic no good and have many issue, they only recommend daikin.

Second shop tell me they have both but panasonic better for house vs daikin.

Both shop giving conflicting information so what are you guys opinion on this ?

2nd shop also advised me not to get inverter for living room as they claim no power savings for living room. Only recommend inverter for bedroom.
