I suppose that is the peculiarities of personal preference. I find the Semogues suffer from disappearing lather and they become floppier much quicker than other boars - that and the construction of their knots which are glued into a conical cup to make them splay - excessively so. The face feel though is excellent from the fatter bristle that they seem to source. Zenith bleached boars use a much finer hair but are lofted too high and feel like a mop - their unbleached boars are very good though. Now a short-lofted Omega's on the other hand hits the goldilocks spot. In any event I find boars are a disposable brush in that they hit their peak for about 6-12 months after being broken in and then become increasingly mushy there after. But when a boar is at its peak and being the best it can be - just tremendous.Omega... I've tried many from the entry level 10066 & 49 right up to the high end (for a boar) 011829, They were all stiff and scratchy apart from the most expensive one which was also floppy due to a severe lack of density lol. If you like thick bristles which provide an aggressive massage and don't mind massive glue bumps and cheap hollow plastic handles they may be acceptable.
For boars I much prefer Zenith and Semogue, who are just as inexpensive as Omega yet offer much higher quality brushes IMO.
