My favorite brush right now is a tie between my H&M Kabuki brush, that I use for blush, and my Essence (gasp!) eye-shadow pencil brush...

Essence Pencil Eye-Shadow Brush
The H&M brush is a bit on the rough side, but not so bad that I wouldn't recommend it to others. It's coarseness is not off-putting, rather, it is comforting to a degree. Its a tough little brush. I've had it a long time. Its been through a lot. Its a great little brush, and it applies blush well... When I wear blush, that is!
My Essence pencil brush is amazing, its small, delicate and oh so soft! Not bad for €3.50, eh? I use it to blend a smokey eye when I'm going out. It's small and precise, and very very good at its job! Cannot recommend this particular brush highly enough. Budget beauty tools don't have to be crap anymore, with companies like Essence cornering a gap in the market. Definitely worth a look, ladies!
