Voron Trident - Which kit is state of th art?

Hi there!

I bought a Creality K2 Plus, which prints really nice. Only trouble is with CFS, where filament changes are often not working good.

For a long time i wanted to build a voron trident. So i think about selling the K2 and building a Trident.
It seems as if LDO RevD or latest SIBOOR Kit are state of the art kits? Will there be improvements or actual changes working on? Is 4WD better more future safe than 2WD? Are CNC-parts better or is it better to take printed parts?
LDO trident is the only kit with z-height above 250mm. I don't know if it is important.

Or should i stay with the K2 (which was really cheap)?

What are your thoughts and suggestions? By the way: I'm from germany, so some kits are no choice for me (West3D, ...)
