Should i keep my Creality CR10-Max

I got a CR 10 Max for free from a frend. It already have Bondtech extruder and BL touch. How is the printing quality of this printer? And is it still worth it to keep. I can upgrade the hot end to a Micro Swiss, Install CR touch. Put all axis on linear rails. He gave me a 5.5w lazer engraver that i can also use on the printer. But is it worth it, or should i rather sell everything and buy the K2 combo. Or should i keep it upgrade it , save up and later on buy the k2 combo with CFS. I appreciate the support.
