Define "Better". What is your most important criteria for an a/cond? Could be anything: Electricity savings, low purchase cost, easy to service, availability of spare parts, fast cooling, etc, etc, etc.

For example, some people want a car that looks tough, don't care that it is hard to park. Some want a car to show off, don't care that no money in the pocket. Some want a car that seats 7, well, that will handle like a barge.

So unless you can come up with what is important to you, this is never ending to try and "convince" you. We'll say an a/cond is something, but you will come up with a "but".
"This is the cheapest a/cond to buy".
"Oh, but it is made in China I don't like"
