The MW process is very straightforward and produces cleaner prints than the B&S process (i.e. no nasty black spots). But, and it's a big but, you've got to have close control of the humidity of your coated paper (which is not necessarily the same as the room humidity). With accurate humidity control you can achieve pretty much any tone you want between blue/black to very warm with pretty much any combination of Pt/Pd.
His approach for clearing prints works very, very well for either process.
As you're in London, Stephen, you're welcome to pop over some time and see some prints made with both processes if you like.
