Yeah, you are right every person has their own opinion and judgment about the teams but if looking at the statistics we found Australia the best team in the test format. Australia and India played Many matches and mostly Australia won the matches.
Today I saw a video on YouTube which was a few months ago but it's not a big deal because nothing gonna change that much that causes one team and the other down. In the video, I saw that Australia has a win rate of 47.50% while India has 30.15% which shows that Australia is better than India. There are many other things in the video here I am giving the
link of the video so you can confirm it or any other person wants to check.
Test importance is declining because of too much T20 otherwise test is the proper cricket. Right now Australia is number 1 test team while India is number 2 in test format with little point difference. Australia are number one in test because they pay much attention to this format. There is BBL going on in Australia but there players including Warner were playing test series against Pakistan. While Pakistan main bowler Haris Rauf preferred playing BBL instead of Test series and result is 3-0 victory for Australia.
