I love the EdT and just got a tube of the cream which I am not too fond of at all for some reason. The scent of the cream smells "off" to me compared to the EdT.
Anyway, to answer your question. I've been using the GFT cream with Speick splash. The Speick is spicy and complimentary IMO and the scent of the speick splash is gone in about 5 minutes so no worries about interferrence with your cologne.
