WebFirst off, the Delta IV does not use the RD-180, you're thinking of the Atlas V. Anyway, the difference is fuel. The Merlin uses LOX/Kerosenewhereas the engines you list use LOX/LH2. Naively you'd think that the increased Isp of LOX/LH2 makes it an intrinsically better propellant, but there are lots of reasons why LH2 is problematic.
