hey there, i have been mixing for a few years now, i have used CDJs, serato and traktor many times over the last few years …if you get the chance to use or own CDJs …TAKE IT .. as it is club standard in 90% of clubs around the world, you can also use serato with turntables or laptops or traktor, if you want … they all seem to work great for playing out or even practice … but it all comes down to WHAT YOU PREFER .. since CDJs and DJM setups are expensive .. most new djs just starting out tend to favor traktor or serato more because its cheaper to get started … i say go with what you have for now .. get familiar with your setup and how each software works.. and as time progresses you will gain your own opinion on each and be able to make a better decision on which to stick with, eventually you will make your own decision on what you like… hope i was able to help 🙂
