1200s all the way, could never leave vinyl for CDs (even though I use serato)
i never really played with CDDJs, but I hear there’s a pretty good set of tutorials on youtube under DJ TUTOR (djtutor.com)
for the most part, learn to use the CD DJs then apply vinyl techniques to it. Learning how to beatmatch is like learning how to drive a car…if you know how to drive one car you know how to drive them all to some extent…I just get confused by all the controls and shit personally, and scratching/etc isn’t so easy on CD players. oh, and i’m guessing zong uses Reason based on that pic…but i didn’t really investigate much.
good luck!
