Depends what you want to spend.
Best are Mac and Bobbi Brown
Middle of the road - Clinique is good and reasonable
Lower end of the market - MaxFactor and Revlon
Depends on your skin type. I have oily skin and use Clarins Multi Matte foundation (think it has been changed now but I still have some of the old left).
If I were you, I would buy a relatively expensive foundation £20-30 and concealer then spend less on the 'accessories'.
IMO, Benefit is thick, greasy and exceptionally expensive for what it is. I don't know any other make up artists that would use/recommend it.
