Fundamentally, what's the difference between MIG and Flux Core welding?

I've always used straight CO2 (100%) when using this method of flux core.
The differences:
MIG, you push the wire
FC, you PULL the wire
MIG, doesn't need cleaning to restart weld
FC, must be cleaned very well before welding.
MIG has no slag
FC has layer of slag, which need s to be cleaned off.
MIG least penetration of all weld types
FC one of the highest penetration of all weld types
MIG harder to weld with
FC very easy to weld with
MIG hard to get appealing appearance
FC, very easy to acheive a asthetically appealy weld...
I could go on...
There are obviously a few PROS to MIG but the PROS of a properly set up FC just doesn't compare.
