CDJs or XDJ?

I'm new to DJing (just 2 months in now), but I've been improving pretty quickly (not to toot my own horn or anything, but I've been getting much more comfortable with mixing songs, and have been improving with working with songs I haven't heard before)

I currently own a DDJ GRV6 and have also recently experienced the world of CDJs and I absolutely love them! My question is should I save up to upgrade to a set of CDJs, or should I get an XDJ-AZ or XZ etc. (I haven't ever had the chance to use an XDJ yet)

From what I've seen, the AZ has a lot of the same features, just that it adds stems and pad fx and such like my controller, but it had the one screen and layout is a little different (that and being almost 1/3 the price lol)

Let me know your experiences and what you'd recommend and I'll continue doing my research too
