I myself am not very fun of rankings. But when the Library of my University decided to cut down some of the journal subscriptions (due to the budget crisis in the Eurozone), I gave my personal viewpoint by means of creating a unbiased ranking of Mathematical Journals.
Mainly what I wanted to measure was the impact of the Maths published by each Journal throughout its life on today's Math. I took the raw data from MathSciNet. The result can be consulted in the web page of the society journal of the Spanish Math Society (the "Gaceta de la Real Sociedad Matematica Española"):

and also in my personal web page:

The paper, where I explain the procedure devised for creating the ranking my procedure, is in Spanish, but at the end you can find the ranking, which is easily understood.
My ranking treats on the same footing all journals in applied, pure and statistical math.
