I love my sheephead and flathead premiers. For show cattle for sure I like them both from premier. I think osters have more power for slick shearing but I could be wrong. The smaller size around and length makes them easier to use.
Premier hands down, even for slick shearing. Last weekend I was peeling with another experienced clipper person who was running Osters and he had to set them down severl times due to the fact his shears were so ho he coulnt hold them.
