It's a good contest. Liszt specialised in solo works, and his technical works were exceptional. His transcendental études with the devil's violinist were incredible, and I particularly adore liebestraum no 3. However, Rach absolutely dominated when it comes to piano concertos. I enjoy Rach's works more because they evoke emotions more than Liszt. In complexity, they rival each other, like no other composer. Possibly with Chopin close behind. They both had humongous hands, but Rach's hands were a bit bigger.
