the mirror modifier or the edit mode mirror

Any one that does the work is cool. I think edit mode mirror is a bit more finicky, so I always use the modifier, but again, any tool that gets the job done is fine.

Omar is correct, but:

The Mirror Modifier definitely wins.

The Edit Mode Mirror is quite ‘buggy’ and even if it wouldn’t have been buggy, it still wouldn’t mirror things, but it would just Transform Vertices that are ‘mirrored’ in a mirrored fashion. I hope that makes at least a little bit of sense.

Edit/Sculpt mode mirror doesn’t mirror geometry. If the geometry is close, it can help to manipulate it, but as mentioned above, if it’s not perfectly symmetrical, things might not work like you expect, especially if it gets turned on when the mesh is not perfectly symmetrical to begin with. Mirror Modifier is an exact mirror… what happens on one side WILL happen on the other side, whether it be adding or manipulating geometry.

Both can be useful, as long as you know what to expect.

I think based on the previous lectures, if you use the edit mode mirror, you only replicate moving vertices/edges/faces, if you extrude or duplicate a face it won’t replicate. Mirror modifier on the other hand replicates all edits to geometry.
