Yucca or Dracaena

So I originally was told this was a verigated dracaena but I'm thinking it's a yucca. Any help much appreciated

 

Looks like a cultivar of Dracaena fragrans (Deremensis Group) (syn. Dracaena deremensis).

 

The Yucca leaves are more rigid and a bit sharp. They are directed upwards. Also, the leaf color is totally different than a Dracaena. Dracaena group has a loose leaf and it's a bit glossy texture.

 

So your think yucca?
