The first reasonable looking source I found (https://www.researchgate.net/figure/Characteristic-data-of-typical-liquid-propellants_tbl1_225022069) gives the following:

LOX/RP-1: 358s
N2O4/UDMH: 342s

Of course these will vary with O/F ratio, pressure, and other factors but this ought to be a decent comparison.
