Comparison of Chanel Vitalumiere and Bourjous Heathly Mix Serum Foundations. Am I correct?

Hi, I put your guide to buying companies cheaper products to the test.  I looked at foundations. In particular Chanels Vitalumiere and Bourjous (own by Chanel) Healthy Mix Serum.  This is what I came up with.  I would like to know if you think my assumptions are correct?

What are the first five ingredients for each?

AQUA (WATER)

ETHYLHEXYL PALMITATE

NEOPENTYL GLYCOL DIETHYLHEXANOATE

CYCLOPENTASILOXANE

TALC

Water

Dimethicone

Cyclopentasiloxane

Butylene Glycol

I’m trying to see if the chanel product is really justifies the price/is better.  

Would it be that the Chanel branded product has slightly greater levels of skin lubricating and emollient product than silicones?  Also, would the 5 ingredients be more refined (expensive) alternatives to those used in the Bourjous?  So justify the greater cost of the product?

If not, I can’t really see how the Chanel is better than the Bourjous.  They are both primarily made up of emollient, silicone, talc/starch and of course water. 

Am I correct?
