What are the pros and cons of DE filtering compared to sand filtering?

After six years in this home with a 15 year old pool cartridge filter, I junked it for a DE filter. I'm very very satisfied with the change. The DE filter cleans the pool quicker, but I did get a larger one than recommended because various notes on the internet suggested getting a larger filter, which means more square footage of filtering medium inside the filter, which means longer durations between DE replacements. I highly recommend the DE filter. I owned many pools in different parts of the USA for 30 years and have converted them all to paper cartridge because it was much less hassle then either DE or sand and I also use an aqua-jet electric vacuum machine. I hardly ever have chemical or algae problems.
