For me a good should dj bring all techniques into play *at the right moment*

Either can be as dull or as exciting as each other depending entirely on when it’s been done. I like both. Long mixing can be great at adding depth and interaction between rhythms and sounds in tracks and sometimes something really epic can happen. However when its like this all the time it gets boring and that’s when I think the cutting comes into play to add a bit more energy and make the crowd acknowledge the dj
