If you're on a budget you can't go too far wrong with Real Techniques. I've not had a brush from them that i've hated or even disliked and the sponge is also a great alternative to the Beauty Blender.
I know a lot of people like Zoeva but i find their non synthetic brushes quite scratchy particularly their eye brushes, a lot more scratchy than even MAC for example.
For liquid and cream products it's always best to go for synthetic bristles as synthetic brushes can handle more washing and suck up less product .Animal hair is traditionally the best for powder as the hairs are more textured and so are more effective at picking up and blending powder products.
For powder products if you can afford to and don't mind using (claimed) cruelty free animal hair brushes I would highly recommend Wayne Goss brushes for the most bang for your buck as they're really high quality, soft and have very functional shapes.
Sigma's new brushes are synthetic hair which supposedly mimics natural animal hairs but I have to say that apart from a few standout concealer brushes which i've listed above I would not recommend them as you can get much better quality for the price.
Hope that helps!
