Please tell me which extruder is better to install instead of the standard one. Judging by the reviews, the black extruder is no less popular than the DXC

The DXC is nice as it has the filament sensor build into it and auto adjusting tensioner. There is a screw on the side though that sets the main tension on it, If you are using things like TPU you dont want it to be set too tight. If you plan on using a cfs system, you would have to get a universal cutter and change configs of the printer. Or use the extruder that comes with the kit.
The tensioner screw almost always unscrews over time unless there is a little bit of locktight on it to stop it from coming out. This is only important when using TPU or other soft filaments as you ahve to tighten the tensioner screw to release the tension on the filaments, pla, abs , petg its not much of a concern if it falls out.
The shop i go to all the time has swopped out the extruders on all their machines for the DXC extruder, so it must be doing something right.
The other one i am not sure of to be honest.
I got the DXC extruder on my K1 Max that works very well.
