Erik ... love to hear your list of why.
I have a Wigo head (similar to but not interchangeable with Tersa) and find it the best planer head I've ever used. It doesn't have the price advantage or range of available knives (different metals) of the Tersa. But the knives are fast and easy to replace and self setting. They give a fantastic cut. New HSS knives are exceptionally sharp and give an extremely good surface on most woods. Biggest downside is that they are loud. I am amazed at how competitively priced Tersa knives are. Machines engineered to use Tersa (knives sliding out the end of the head) would seem pretty hard to beat from a price/performance and operational (knife changeout) perspective.
