I did tons of research on controllers and actually took about 2 years to make my decision. Neptune's track record of reliability and customer service is far and away better than digital aquatics. It's not even close. I never had any issues with my RKL but the apex Jr I had and lite I own now are just better made. The power strip is made of metal (doesn't sound like a big deal but it is.. much safer) and on almost every site out there, the Apex is recommened 9 times out of 10 (or more).
Some of the programming is above my ability and patience level but the most important part of a controller is the reliability. If something breaks you're in serious trouble. There's many more stories of issues with DA products (that I've seen) than with Neptune.
Plus, they're quicker with updates, have more features, modules, functionality, etc.
Your milage may very but that's what I feel. If you want to go with digital aquatics, by all means go for it. It's not up to me or anyone else (other than the companies) to convince you either way. At the end of the day you'll have to do the research and make the decision.
