I don't think it's necessarily better or worse than email

It's greatly worse than an email because it (1) primes the candidate with a false set of a (highly positive) expectations, only to simply (2) gouge very significantly into their time (as with any scheduled video call). The fact that these companies have no grasp of what should be obvious to them -- in particular as regards item (2) -- is central to what's so toxic about the current job application process.
