I think it also depends on the music you play. I never really looked into DJ pools. I always thought that was more for top 40 and hiphop and r&b. I play deephouse, house and techhouse. And I really like Beatport for that. I think beatport and traxsource have so much more choice in those genres. But I could be wrong.
Maybe someone knows a good DJ pool for deep and tech.
If you can find the music you like on DJ pools then I would say go for it. I understand that you like searching for music. I do too. But is not some “way of the DJ” that you have to do that. Back in the day I took the train to Arnhem ( a city in The Netherlands ) once every week 30 km from where I live. Then I would visit the 3 record shops there. That was great. But expensive. Now I’m buying music from the same chair I am sitting in now. That is also great, but different, and cheaper. And there is nothing wrong with saving money.You can always invest that in more money or DJ gear. Or groceries 😀
