I totally get your question, I often wondered myself in my early days. In all honesty, I am still learning a bunch. The only thing that will make you know what is what is experience. I have grown so many strains over the years (thanks to single seed marijuana canada) that I have learned to recognize what hazes are, the diesels, the strawberries, the blueberries... The only way to figure out for a new grower is to grow a lot of said varieties and make connections. I have grown super lemon haze, super silver haze (from various breeders), dragon fruit, etc and then you start to pick up on that sumac lemon smell that makes a haze a haze. It is a life long journey, and I am still learning.
One thing I know for sure is no one has the best strain, it does not exist. Nowadays, you are likely to find an OG with the high of a haze and a haze with the high of an OG, it doesnt matter anymore, find what you like, grow it, make seeds, grow it again, mix it with other things you like. END.
