How do I pick a good paint brush?
For a professional, it's all about economy, and that doesn't mean brush price. That means project speed and finish quality. 

A great brush should:


Carry a lot of paint without dropping it
Allow consistent, smooth application of the paint film
Provide very good edge control
Feel good in the hand
Offer a comfortable, secure grip
Function well with the user's preferred techniques
Last through multiple jobs without frizzing or bristle loss
Clean up easily and completely


It isn't about features, such as shape or taper or bristle material, because what's needed varies by painter and by project. It's about benefits in the way of performance that save time and money. 

Just as I can't tell you what shaver or deodorant to use, I can't tell you what paint brush to buy. Try a few and learn what works for you. It's a safe bet that neither the cheapest nor the most expensive are the right one.
