Those mentioned are good for different reasons. Some people like their music played certain ways. Janis and Wild are faster, with Wild brilliant and Janis more fleet, and both colorful. Cliburn and Ashkenazy are slower (Ashkenazy may only seem that way because of the smooth performance - I didn't check the timing), with both still exciting, but more opulent (Cliburn) and liquid (Ashkenazy). The Richter is a mix of various tempos, sometimes stately, sometimes exciting, but it works. Good luck, happy listening.
