This is why I am a Badger fanboy. I'm sure Paasche and Iwata are great brushes, but Badger will always go the extra mile.
Here are my brushes:

Typical painting setup. All brushes have a quick release valve.

Omni Vega left and a 360 right. I use the Omni only for very fine weathering and dye.

155 Anthem. This is my general purpose brush. I use it for larger projects such as painting multiple models or a large shell that would empty out the cup on the 360.

My 200 does not get much use these days.

The 350 is cheap, but works well. I think I bought this for under $18, which is even cheaper than the Chinese imitations. This is a great brush for scenery work as there is very little cleanup needed. Spray pattern is nice and wide but still controllable.

And finally the Badger 250. I buy these in bulk from the Badger garage sale for about $5 each. The larger version is great for applying bulk color to a layout such as earth, concrete or pavement. I also use these to spray ballast wetting agent, diluted matte medium, and other adhesives.
