If you enjoy building the Voron that’s definitely a better deal (and I think I would) but if you’re doing it to save money you have to factor in that time in the cost as well. I was briefly considering buying a Core One L after they become available with INDX, because it would be nice with a printer which includes everything and just works. But the VFA problems discouraged me, Prusa’s suggestions to overtension belts and modified slicer profiles which try to avoid certain speeds feels like a bandaid solution to what is fundamentally a hardware design flaw IMO.
