Virtual Wire TAG Allowed vs VLAN Subinterfaces

Hello good morning, here again to ask some questions and review some doubts, thank you very much for the collaboration and good will as always.

In relation to the use of Virtual Wire, what is the reason to use, in VLAN environments, what is the reason or advantage and/or disadvantage at vmware level to use for the vlan TAG, the Tag Allowed option vs. use Subinterfaces layer 2 and set them there each TAG ?

What is the advantage, disadvantage and/or in which situations to opt for one or the other option ?

Thanks, I remain attentive, greetings and attentive to your comments,
