I use the French tradition so I shall pick this book. I've seen reviews on the internet (like Donna Leigh) and it does look good, but they don't mention which tradition. I don't see the point of getting books from other traditions.
It depends on what one classes as a French 'tradition'. Rana's book uses the Fox for salaried work et cetera. which has been popularised in French language books post-1960s (Silvestre etc). Fox as a work card actually has its origins in Belgium where a lot of the French literature and poems come from before the 1980s.
Rana herself says about leaning towards the French/Belgium et cetera angle. But even if you were a student of Treppner you'd be able to work with the book and take something away from it. It is very good and I highly recommend it.
