J M Fraser. I view the question as the cream to judge all others based on results and price, not necessarily the cream to beat all creams.
My all time favorite is Trumper's Rose, just for the smell alone. Smells like a fresh rose in the garden. I like to save it for special occasions. I really can't say it gives a better shave than Fraser's cream, at least for me.
I should also add that Tabac is very good and I can't say another cream gives me a better shave.
