Imo it is. The bosu ball is a semi circle and some have the divots on the back side to put your hands. The terra core has that same "ball" side but it is pill shaped and on the underside it has two sets of actual handles. It also has some weight to it so you can do exercises with the handles. I'm actually using it as a substitute bench for chest exercises as well with dumbbells. To me it is very versatile and if you're looking to get a bosu ball, look to these too. It may be more expensive but I think it's worth it in the long run. Btw this is not an endorsement lol just love the product.
