I've been DJing for about a year and a half (although new on here) and I use VDJ Pro. I've played around in Traktor, not so much with Serato, but I find them to be less user-friendly and find that I work faster and more effectively in VDJ Pro.
However, I've noticed that VDJ is less-common and there are a lot of people with stanky opinions on the software. I hear all the time: "VDJ? Nah, I'm a real DJ, I use Traktor/Serato." I realize everyone is entitled to their opinion, but OBJECTIVELY, am I missing something?
