so far I've tried 3 boars and 4 badgers of various grades and if I was to start all over again,
I'd be quite content with just 2 boar brushes. They are substantially cheaper yet no matter the price,
the boar tips are never scritchy no matter how strong the backbone. Unlike badgers,
scritchiness is inversely proportional to price.
I have the Semogue 620 and 1460 and I'd recommend the 620 or its equivalent 1520 or 1438.
The 1460 (or 610) have slightly less backbone but still much more than say a pure badger.
At $15 for the wood handle Semogue, I see why they are a favorite on B&B. The Omega boars
are even cheaper but the handle is usually light hollow plastic.
Here's a chart comparing the Semogue models:
