Why Vanicream over Cerave?

I’ve just started on Taz, graduating from Adapalene mid-June.

I’ve been researching on this sub but found some conflicting advice.

1. People seem to like Vanicream over Cerave (I think they are referring to both the lotion and creams in the tub)
2. Ceramides are important for barrier support

Cerave has 3 ceramides, so shouldn’t it in theory work better with taz/tret than Vanicream? Is it a good barrier cream?

If you use Vanicream, do you use a separate barrier support cream over it?

I’ve been using Cerave PM layered with Cerave in the tub for years now. I don’t love the cream in the tub, it doesn’t really absorb into the skin but it always got the job done. I want to be prepared in case it’s actually not repairing my barrier now that I’m starting Taz.
