"Best" is relative. I don't think that the Thäter is better than the Italian Flag (IF). Nor do I think that the IF is better than the Thäter. They are different brushes designed with different philosophies. The Thäter is designed more like a badger while the IF is more like a barber's brush.Ciao @Cino
Thank you for the feedback. I was wondering which is the premium boar brush by Omega. Is there any better than this model?
I have also an Omega 20102 which, I think, is the same knot as the'49, although I've read some reviews claiming that it is better bristle. Though the least expensive of the 3, it is also a wonderful brush, just different. I personally wouldn't part with any of them.
To answer your question, in my limited experience, the IF is the premium offering by Omega and could be considered their best (at least in the US). It is the most unique but also requires the most break-in to make it behave.
