RFH and delta t

On radiant floor systems for residential applications what delta T do you want? I have heard 10 degree's and 20? Is either one o.k. and it just depends on the design? Would the 20 degree delta T produce heat faster and 10 degree delta T maybe have less temp. fluctuations in living space? What are the advantages and dsadvantages between the two? Can you change the delta T just by circulator gpm?
