Blade choice does matter. Timeless Bronze .38 hasn't been my favourite. Feather blades are my go to. Results with that razor = meh. Put a Gillette Platinum in it this morning... Purrrrrrrrr. BBS super tasty extraordinaire.
I'e discovered the same. I started with an EJ badger, bought a synthetic tuxedo from AP ShaveCo and was disappointed in it, bought and used a Semogue boar. Now that I've come back to the synthetic, I find it excellent.My first brush I bought was a synthetic brush I bought at Bed Bath and Beyond for like 10 bucks. Since then I've bought a pair of Omega Boars, and I love them.
Used my synthetic for the first time since moving to Omega brushes and it turns out that my synthetic brush is exceptional.
