When I started the salon I used orly but found the colour range limited. The polishes were great though, went on lovely, kept nice in the bottle, and lasted well. I now use OPI mainly and both the OPI and orlys I have left last very well on the nail. The colour ranges now though from orly are gorgeous! They've a violet pinky colour I saw on a client and it is fab! Maybe get a few of a few brands and see how you go. I use OPI, but I also have some essie and some creatives. Both lovely to use. hth x
