I just changed out my existing ABG, and I considered Radiant. But for a number of reasons I did not go with one.
Price was one, and was also the same reason I did not go with a 100% resin pool either - If I was younger, and my kids were younger, and we were planning on being in this house for decades more to come, then I think the extra money would have been worth it. But when we looked at warranties and expected longevity we were making comments like "that pool will be around long after we leave this house, heck it will be around long after I am dead".
The other thing that really bothered me specifically about Radiant was the lack of information. Their website is fancy, but tells you precious little about pricing or where to get one. Apparently the only place I could get on is from some local dealer I never heard of, who took almost a month to email me when I submitted the online form (As opposed to my Bullfrog Spa dealer who called me the same day).
I do really like the idea of the Radiant, and if I had gone with the Radiant I would have likely saved money by installing it myself (as opposed to trying to manage a 250 lb floppy steel pool wall on my own, or arrange enough help on a day with everybody available and weather playing nice) but the price and lack of response from the dealer really turned me off.
