There is only a ~$100 difference in price between the two if comparing the combo of light+mount, and less if you only compare light 2 light. Most would claim Radion to be the gold standard in the LED lighting world. 25% difference in cost... 15% difference if reviewing lights only...
Accessories are optional, and subjective as to their form and function. Heatsink comparison is sort of laughable. Does the ReeFi have a BIGGER & BETTER heatsink, or has Radion figured out a way to be more minimalistic with greater results than the competition?
With more knowledge out there, it makes it easier for everyone to make their own choices. In this case though, the OP wants suggestions to remedy his problem with glare and not with dropping 1500$ + in buying a so called comparable setup that will STILL have the glare in his/her situation.
I will say that your 6 Uno setup is rather nice.. your whole setup looks pretty legit!
