Each has their uses and limitations. I wouldn’t necessarily say POM is the best. Tessellation has advantages over POM, but requires a well tessellated mesh to begin with to be able to obtain the detail, but you get shadows, proper decal placement, proper raycast hit (if you want per poly), etc. POM has issues with these, except maybe self shadowing. I never liked in cryengine for example where they used POM on the terrain, sure it looked nice from one perspective, but looked awful from others and when u shoot at it, u get floating decals.
