I love the Trumper Sandalwood scent and the soap is an excellent performer. The scent is nothing at all like the QED Sandalwood which is a pure Sandalwood scent.
I can't describe specifically how Trumper differs except that is is more complex than the QED, almost like it could be a cologne. It is hard to identify sandalwood scent in the Trumper if you compare it to the QED.
I love Trumpers Sandalwood Shaving Soap and use it very often. But I don't know the others you mention. I allways use it followed byTrumpers Sandalwood Skin Food as aftershave and that combination gives me a very descreet scent of sandalwood, which I like.
