Quaternions or Vectors: Which is the Better Choice for Electromagnetism?

[Gerenuk]

I read that people prefer vectors over quaternions (e.g. for electromagnetism), since one can do the same operations more transparent. Is it really a matter of preference? What's advantages of one or the other?

Actually, differential forms together with vectors appears to be the currently preferred "flavor".
