Apologies if this should be in the brush section. It's a brush question, but also a newbie one, so I'm happy to be corrected. I currently have a cheap boar brush from Walmart (VDH?). While there is nothing "wrong" with it, at what point should I upgrade? I have the cheap puck the brush came with, and also some Proraso. I find that I've been much happier with the Proraso. Will I notice THAT much difference with a nicer badger brush? I also have on order a sample (Musgo Real, Talbac, Taylor Lavender, Taylor Sandalwood, Trumper Rose, and Truefitt & Hill West Indian Limes). I'm not against getting a badger brush, just want to make sure I'm doing it for the right reasons (other than just helping the economy).
As has been noted elsewhere there is no real switch over point, it's not as though the DE shaving Jedi master comes to you and says "Now my young padwan to become a full Jedi shaver you must prove yourself worthy of the badger".
In my case it was when I found the Shea Ultimate Shaving Brush and later the VDH badger brush at under ten bucks.
If you want one go for it, boar has it's good points (my old VDH boar resides in my dopp kit) and badger has it's strong suits and that ten buck VDH badger is still going fine.
