FML : I have two mixed badger/boar Semogue brushes (2013 Mistura and 2012 Owners Club Special Edition) and I love them both. I don't have a pure boar brush. Is there a particular brush you would recommend above all others?
It is a matter of taste and personnal preference. For instance, SOC is regarded as the best boar brush, but you will find a good all around brushes in the Semogues 830 and 1305, or a firmer version in the Semogue 1800, or softer versions in the Semogues 1250 and 820.
If you like big brushes, the Semogue 2000 is a little taller and less denser/firmer than the SOC. If you like small brushes like the Mistura but with less splay, you have various models to choose, with a loft of 50mm and a firmer banded hair or a softer white/yellow hair.
The downside of boar is breaking in. Sometimes, months of daily shaving, like the SOC. But you will be regarded with a brush almost as soft as a best or silvertip badger, for a fraction of the price and some elbow grease.
I cannot recommend you one brush, as I stated, it is matter of taste, but I have almost one exemplar of the knots available from Semogue and I find myself using more the Semogue 830, perhaps because I like high lofts.
