All the brands you mention offer quality boar brushes. I own two Omega modern beehive two-band boar brushes and consider them two of my best brushes. My only complaint with them is that the handles are hollow plastic. I also have a Semogue 830 boar brush which seems to have taken a bit longer to break in than my Omega boars, but does an excellent job crafting lather from a puck of shaving soap.

Finally, I own a Vulfix 404 Grosnevor Boar/Badger brush. No complaints with it. I believe that Vulfix also makes some excellent all boar brushes too.

I hope that this helps.
