In my opinion any brush..... and Fifty Series
I was going to suggest the 50 series (even had it listed)... but... I have no personal experience with them and from the specs the loft is a little lower then the others I suggested, which I do have personal experience with. The H6 can stand toe to toe with my Kent BK8 which very few brushes can do
Why do the Simpson branded shaving bowls cost so much - I mean it is just a piece of pottery with their name slapped on the side????
It's the brand that costs. It applies to their brushes as well.
