I just got mine last night, but compared to my cousin's AI sol blue I would say go ecotech 9/10. The fixture seems a lot brighter and the programming option is awesome. I say 9/10 simply because out of the box it takes some getting used to the software, but overall easy.
You could almost buy 2 AI Sols for the price of one Ecotech and quite honestly in my opinion they are NOT that much better. I got the opportunity to see them side by side the other day, alot of hype in the LED game especially with big name brands, just because they make the best wave makers doesn't mean they make the best LED fixtures, just my 2 cents.
