I ordered the 16 ounce hammer, but Amazon Warehouse Deals sent me a 20 ounce by mistake. I decided to keep that one, and I'm glad I did. The 20 ounce feels good, is well balanced, and seems to be easier to handle than the 16 ounce version of other hammer brands (I've used the same  Stanley for 30+ years). I think I like the curved claw better than the straight claw, but that's just because I'm used to it. I use a wood block as a fulcrum for the straight claw, which is actually better on the wood.
