I have AI. Radions seem to be considered the gold standard for LED lighting. But if you look at the specs of both, radions have an edge but not a big one. And many people are quite happy with good lower end LED units.
I would suggest checking the par in your tank. I run AI units and I have just a bit more lighting per square foot than you do and I grow montipora and acros just fine.
LED lighting has a drawback in being a point source and producing a shading problem for parts of colonies in the shade. People make up for it by adding more units (more light sources and less shading) and if it is too bright, dialing down the power some. Some people go whole hog on this and get a pile of AI primes but I think that is over kill.
I would suggest just adding one or maybe two more AI 24s but you will probably get AI 32s As the 24s are being phased out. Or you could sell your AIs and get Radions but I don’t think that there is not that much difference.
Another thing you could do is go hybrid. You could keep your AIs and add a T5 fixture or two to boost coverage and intensity.
In any event, I would recommend getting Par measures on your tank. If the par is ok, then you don’t have to worry unless you want a couple of units to give more even lighting. Without measuring par, you are guessing.
