If I see a profit side, USD / JPY should be my favorite pair because I have gotten a lot from this pair. Overall the EU is my favorite partner because of its liquidity. Today my favorite pair is USD / CHF because my trade is in this pair, hoping to make a profit. and my best partner is USD / GBP, the reason for this pair is that the ratio of up and down pairs is very slow and you can judge easily, and practicing demo accounts is more important for profit.
