They are techno examples but you could try this site for lots of different EDM course:
FaderPro is not free but it is very good and they are real courses, from real Producers like Roger Sanchez. Many different styles too.
Also there are several ways to make an EDM kick from just using a plugin like Kick2 or layering 2 or 3 kicks.
But there is no “right kick for every track” as it were. In techno you might build a kick and then create the drums around that kick as its the main thing in the track. But in house you might try 20 or 30 kicks until you get one that works. You might build most of the track and cycle through kicks later on in the process to get one that suits the track better.
Obviously longer release on a techno kick and a shorter release on a house kick.
For phase, if i am layering kicks i will only have one kick with a lot of low bass. I will EQ the bass out of my other two kicks. I try to eq each kicks to suit the part of the final kick it will end up being. But i might use a hat blended in at the top of the kick. So for phase, if needed, I use a plugin like little labs and I will be blending only two kicks and I’m listening for when the combination becomes the loudest. But mostly i will eq the bass out of the mid kick and the low and mid out of my high kick. I find trying to blend the bass of two kicks together difficult and not rewarding either so I don’t do it. But I do use phase to fix bass issues etc so its a useful technique.
Really you need to do 5 or 6 courses and you will pick up your own methods that suit you best.
The problem you might find on youtube is ppl who have never made a good track in their lives are giving advice. Be careful because there is some good stuff on youtube but also a lot of terrible advice.
