DDJ SX2 or DDJ SX3

Hello, lifetime Pioneer product user. Going to upgrade from my tried and true DDJ SX, and would like any successful users of the sx3 to chime in.

I currently use a mid 2012 Macbook Pro I7 2.7 16gb 1GB nvidia 650m OS Sierra. Latest version of serato pro, and serato video. it runs flawlessly 5 times a week 5 hours+ each shift. for the last 6 years. I really want to upgrade and have the $ to do either sx2 or sx3.

 I really only wish to hear of successful adopters of the sx3 along with any specs they may be using. There are no shortage of negative threads about the problems many users have had, so I don't need them to give a response. 

I just wish to know if the problems were an anomaly and people have adopted the sx3 and have had no problems. I have no room for error, as this is how i feed my family. Thank you in advance.
