If I had to split multiple cords of wood every year, I'd buy a power splitter. For smaller amounts, there's just something. . . satisfying. . about splitting logs by hand. I bought a Fiskars X25 last year and it's fantastic.
While driving down the road today I got to thinking, if I were looking at getting a new splitter today, would I get one with the wedge on the ram (like I have) or get one that pushes the wood into the wedge.
