krypton_john's right - there is no comparison! They're like chalk and cheese
A 5 seat modern turbine with glass cockpit, compared with a 4 seat piston designed in the 80's?!
One looks gorgeous, the other is butt ugly.
One sounds like a helicopter, the other sounds like a tractor.
You pays your money, you takes your choice - the R44 is great at what it was designed to do and for the market it was aimed at, but is a class apart from any EC machine.
