I have never had any radio failure (apart from one Hitec servo) ever, but I have lost many planes to RF link loss, even on Futaba FAAST.

I agree that combiner box is a single point failure, but if its reliability is much much better than the RF link reliability to one receiver is, then it is a net positive in my opinion.
