These are my first pair of blocks so I can't write a review to compare these block from others. What I can do is share what I do like about these blocks:- These blocks are very light. Easy to carry and transport if necessary. Light enough to comfortably use between legs if necessary. - As light as they are, they are also very sturdy. I was able to lift my entire body pushing down with my hands, blocks sideways/vertical, without any kind of wobble. - Texture. The blocks have a smooth but non-slippery texture to them, so when you push your hands on them, flat side down, you will not slip.- I went back and forth between the 4 and the 3 blocks but I'm glad I went with the 3 inch. I weigh a buck 55 and these were perfect for me. The 3 blocks are also easier to grip when doing pushups or any other pose that requires you grab the block.
