OIL CHANGE IN automatic transmission. WHICH ATF LIQUID IS BETTER - ORIGINAL OR ANALOGUE?

Is the oil in the automatic transmission the original or the analogue? When choosing a fluid (ATF) in an automatic transmission, many motorists choose an original oil for only one reason. Fill in not the original - the automatic transmission will soon break. Let's figure it out - is the original automatic transmission oil the best choice or not?
I would like to understand this issue, for at least 2 reasons:
1. Why absolutely reasonable advice: It is recommended to use the original liquid, long ago replaced by the statement - that nothing can be poured into the box except the original!
2. Not everyone has the ability and desire to overpay for the original liquid, it costs much more. And there are also those who have a question not even about the price, they are just looking for the best product for their car.
