Preferred Guest Verification solution? Trustd.ai vs Authenticate vs Truvi vs ... ?

Curious what other hosts are using for guest verification?  I don't need anything to extensive but just a little peace of mind with direct bookings where I don't have airbnb providing any vetting.

Trustd.ai sounds seamless but maybe untested and too reliant on AI getting into everybody's business.  Authenticate and Truvi require extra effort by the guest but seem to have a more established track record. 

Or another solution I haven't considered?

Appreciate your feedback. Thanks!
