I prefer the 4 wire install, how many here would wire a outlet with the neutral being ground too?

Would you prefer it if it costs $1000 extra to run a new 4 wire cable
back to the panel? The comparison with the outlet isn't a good comparison,
because it's never been code to wire an outlet with the neutral
and ground shared. In the case of existing oven circuits, it's permitted
and common. From a technical perspective, a general purpose
outlet is typically different than a dedicated hardwired oven or oven
receptacle. In the case of outlets, there are typically multiple
outlets, lights etc on a circuit, more places for connections to come loose or
other problems to crop up. In the case of an oven, the shared neutral/grd
is on a dedictaed 8 gauge or better cicuit from the panel to the appliance.

Is 4 wire better and required for new circuit runs? Yes. Would I
go changing an otherwise adequate 3 wire circuit to 4, just to replace
an oven? No. Apparently all the oven manufacturers agree, because every
oven install manual I've seen shows how to connect it to either a 3 wire
or 4 wire circuit.
