brother in my experience, dawlance works fine without any issues over the years AL HAMD U LILLAH.
however upon physical inspection of the 2 AC units i think TCL is more quality product besides it has orignal features included like advertised on the website and its the same model as per international standard that is being sold anywhere else.
however dawlance are local spec AC units.
you can decide accordingly.
going with either of two is fine. i would have chosen based upon price, whichever costs less makes more sense.
