I like my radions but maxspect puts out a good product. I went with radion for a few reasons. First they have alot of versatility when it comes to color combos from 5k to 20k and everything in between with the push of a button. Second ecotech promised this model wouldnt be replaced and instead would have an upgrade path so I wouldnt have to ever buy a whole new fixture as tech improves but buy the upgrades they have released new led configs, tir lenses, and additional channels already. Lastly ecotech has an outstanding reputation and great customer service. I think any route you take you will be happy. Just look at the recomended mounting heights of each fixture, light coverage, and things you know you want in a fixture. No two fixtures are designed for the same application the radion is designed to be mounted pretty low to the water compared to some other fixtures so it may not even be an option for some people. Read, compare, and make ONE purchase thats all a guy can hope to do! Good luck!
